Fellas! I just have to tell you this, its probably old news to most of you but anyway. As you know i have been having problems lately (yet again), the symtoms were many and hard to make out. Well today the ba***rd fouled again and wouldnt run properly just like it was running on only 3 cyl. We are now 110% certain that its the petrol causing it. What happens is when the engine has reached normal temprature and i stop (with engine running) or drive very slowly the temp rise very fast (15-20F) and the engine starts fouling.... MORE
Jens... Dyno There ya' go!!! About time!!!! A dyno session(s) is part of a "tuned" engine rebuild. It's the last part, to be specific. The ignition advance curve (rate) is exactly opposite of what works in a mildly cammed stock engine, considering the cylinder filling characteristics (torque curve) of the "hairier" performance cam profile is "back to front" when compared to the stock cam. PCV valve Again, are you running the factory stock intake manifold mounted PCV valve fed from the can on the timing chain cover? If you are, and it is "new", it MAY be "NOS" or... MORE
Hi In the process of rebuilding a tandem (dual) MC from early Sprite. Noticed that the pistons in these were painted/coated in black. It is wearing away on mine, some of it is fine while some is gone. I was just going to steel wool polish them smooth. What were these painted with? something not affected by hydraulic fluid. Should I just bring them down to bare metal and forget about it? Have alot of time and $$ in this with resleeve so I want to do the right thing. Mike mk2sprite@... 33286... MORE
The oil going into the combustion chambers will also reduce the apparent octane of the petrol which won't help matters. David "David Jacobs" 33280... MORE
"oil in combustion process...reduced octane" Most assuredly so, David. Yet another symptom we knew nothing about prior to Jen's last post. I had no idea it was blowing blue smoke. This is "wearing me out"!! :):) Cap'n. Bob '60 :{) PilotRob@... 33283... MORE
Jens... Timing..... I am an adult. So talk specifics to me. How "overadvanced" was the total timing from 30 degrees? Give me numbers. PCV valve.... Assuming you are running a stock intake manifold mounted PCV valve with a rubber diaphragm (and it's compatible "filtered" plastic oil filler cap), excessive oil burning would be the product of the rubber diaphragm which has become "porous". They can "look good" even when they're worn out. Replace same and you're done with this. :):) Cap'n. Bob '60 :{) PilotRob@... 33278... MORE
"hard starter" Absolutely, Jens. Enough to ruin the engine in very short order. :( That's why my recent previous post was couched in strong terms as in..."get the job done". As little as 4 degrees over- advance can cause combustion temperatures that can burn through the piston crowns in about 10k miles. Ask me how I know :):) Cap'n. Bob '60 :{) PilotRob@... 33269... MORE
Hello Guys, Can someone give me information on Front Panel Assy for 1976, 1500 Midget... there is one up for auction on ebay with Part# 455-155 in the Moss Book, i dont currently have a Moss Book and would like to know if this piece would be what i am looking for to replace the Front Panel on my 76. Thanks for your time..... Kerry "rumblefish1955" 33263... MORE
Jens....STOP!!! Your chasing yourself in circles here. The variation in cooling temps with the mixture variations, along with appearance of the plugs and most of all, detonation/ pre-ignition (with octane changes thrown in for good measure) suggest the engine is operating on the borderline of self- destruction, in short time. Saving pennies on octane is extremely penny-wise, pound foolish. With a tuned unit utilizing high rpm's a good part of the time, "economzing" on octane can shortly become extremely expensive. Your "tuned" engine is an investment. Feed it a proper and appropriate "nutritional" diet. :):) May I suggest..... ...firstly,... MORE
Jens I told you it was well worn! The other spindle wasn't nearly as bad, but decided to replace the pair of them while I was doing it. Clean the carbs? Nothing more than elbow grease! I washed them down thoroughly several times with turps (kerosense) using an inch paintbrush and changing the turp's when it got too dirty. I then scraped off the gasket material with a stanley blade and rotary wire brush cleaned the gasket surfaces only. The rotary wire brush is too harsh for the soft metal casting surface of the carb itself and leaves scratches... MORE
Just a note for the archives: If you need to buy hub caps for your Minilite replica wheels (such as Minator brand), the ones from Vicky Brit are plastic and don't fit, and the ones from Moss are metal (I think) and fit well. Just my experience. You will need to buy the MG logo stickers top the hub caps separately from Moss. Steve Steven Michelsen 33194... MORE
For the purposes of discussion on subject engine with 1.25" carbs... There are two types of needles.... "fixed" (no jet interference) & (emissions/later cars) "biased" (spring loaded...runs against jet's inner core...) The fixed needle should experience no wear as long as the needle is correctly centered within the jet. Theoretically, they never contact and in this respect, should not wear. The "biased" needle/jet is a contact set-up and thus wears, requiring replacement from time to time. I forget which metal is softer and what wears first (or most, over time/use). The stock jet is always size .90 for the... MORE
My book says that the D3 was the std needle in 62-68 MG 1100 (1098 cc) using 2 HS2 carbs. The numbers are as follows: AN D3 1 .089 .089 2 .0855 .085 3 .0827 .083 4 .0807 .081 5 .0787 .080 6 .077 .0794 7 .0753 .0785 8 .074 .0778 9 .073 .0745 10 .072 .0764 11 .071 .0721 12 .070 .075 13 .069 - Bob Troutdale, OR "Robert Webb" 33161...

Hi The 14W wiper motor was made in single speed and two speed versions. This is the round motor can type located under bonnet. Anyone changed their single speed wiper motor and switch for the two speed versions? I have the two speed wiper switch and a two speed 14W wiper motor. Someone told me the single speed motors only had 4 out of the 5 terminal positions fitted whereas the two speed ones had all 5 terminals present. Wrong. My old single speed motor had all 5 terminals fitted but not all connected. The two speed one has... MORE
Hi all, Is there a recommended torque setting for tightening down the nut on a front spindle to hold the disk brake rotor on? I have the old Brit Leyland ring-bound Spridget shop manual (circa 1970) and there's no torque spec in there. How tight is adequate, and how tight is too tight, i.e. shortening bearing life(?) or some other problem(?) Some background info for anyone patient enough to read - I've got the Frontline larger disc brakes installed, with all new wheel bearings, and yes, the bearing thrust orientations are correct. But seems like over the past year,... MORE
Dave Back on line now. Yes I do. How easy would it be for me to drive up to you and swap over the manifolds. Practical or not? What tools would we need? How long to do the job? Waht should I do in advance like make sure the manifold bolts are not stuck fast. Soory for the delay will send my mitigating circumstances direct to you. Thanks Terry "terry.isherwood" 33101... MORE
Don, You can lower the front buy installing non RB front springs and if that dosen't lower it enough put in spacers between the spring pan and the A-arm. Spacers can be made from some thick (1/4") wall pipe/tubing and longer mounting bolts. Cutting down the front springs would be my last resort. For the rear a spacer block between the axle and spring. The spacer would be a block the width of the spring with a locating stud on it's top to fit the upper spring plate and a hole in the bottom to clear/locate it on the... MORE
Hi folks I know this is a long shot, but you never know till you try. I'm getting close to the stage of slinging the engine back in and will need an engine hoist to do it. Does anyone have an engine hoist they'd kindy let me borrow for a weekend near to NW Surrey? Thanks Nigel "amukdigiphoto" 33086... MORE
Now I had to replace this bit last month and just could not believe how easy it was to fit. I was ready for a real struggle. Plenty of washing up liquid and an ordinary not too sharp, non serated dinner knife. Laid one tongue of seal into grove and used the knife to press home the other tongue of seal half inch at a time and just worked my way along it. Knife needs to be blunt to stop cutting the seal. I did have to clean up the metal around the holes for the corner fixing screws... MORE
Hello just like to introduce my self. I am based in St Neots, Cambridgeshire and am currently restoring a 1972 Midget. Just found the group and had to join, have found them a great help in the past with other restorations. See my work at www.dmc12.tk. please sign the guest book whilst there. Talk soon Paul "paul572151" 33031... MORE
Hi everyone This is a question for anyone with a desmoged late model 1500 engined Midget. As I have kept with original on my '79 1500 I am in need of what is called the Air injection tube for this emissions system. It is a aprox. 1/2" metal tube that runs from the air pump check valve around the back of the cylinder head and screws into the exhaust manifold. It has a large fitting at the manifold and where it fits into the check valve. It is NOT the air rail type tube with the 4 branches to... MORE
Putting the seal in the bottom of the windscreen, needs lubricant. Before putting the windscreen on the car, put a calking along the ridge. They are know to allow water to come in under the sindscreen. Groments... I found most of them at a local hardware store, a very good hardware store, but still local. Foam under the heater box?? Moss doesn't show them in the cataloge here, I have never seen any, so I made one out of cork gasket material. It works, and you can't see it. I'm going to leave it there. Bob, Troutdale, OR "Robert... MORE
I used a plastic push stick, and a bondo spreader, to get it positioned, to sit flat enough to bolt the windscreen in place. You will also need about 3 mates to stand in the cockpit and hold the screen down, once you get the seal where it needs to sit. Brad "" 33015... MORE
Hi folks Does anyone know of a supplier of rubber grommets, specifically those used for where the wiring loom passes through metal holes in the bodywork? I know Moss do them, but I'm reluctant to spend =A32.75 (5 bucks) for a round bit of rubber with a hole in it! Likewise the foam seal for the heater box into the batteryshelf. Moss want a whopping =A34.95 for this (9 bucks) which I refuse to pay, I'll make one myself if necessary. Thoughts? tia Nigel "amukdigiphoto" 32996... MORE
Guys - Currently working on a Buick 215 powered MG midget, always loved the looks of the spoked wheels on British sports cars, but how long will they hold up to a small V8 and manual trans? A friend has offered me a set of wire wheels which he says are from a Triumph or maybe a MGB, (I think they are 14", but how do you tell what they are from, and what splines I will need?) I haven't seen them for a couple of years, hope to get them home this weekend. Was wondering if it'd be... MORE
