I plan to throw out my mechanical fuel pump on my 62 948 engine and replace it with an electronic pump. This pump model on e-bay ( http://tinyurl.com/2l72d ) has been there a number of times but I wonder if it would be a satisfactory substitute for the SU solid state version. Any thoughts? I figure I'd worry about getting mounting brackets later. Nelson "witstock7" 31861... MORE
I can say one thing.. one DCOE on a 1500 is not much point. You should use two!. Second thing, don't bother with the choke on them unless you are firing up in artic conditions all it will do is flood the engine. Last thing don't bother with anything bigger than a 40 DCOE, 45's and 48's are all well and good but all they will achieve is more fuel use and no extra performance. Stewart "Ford Prefect" 31849...

Jim, TRY PUTTING IN MORE GAS BEFORE YOU TEAR IT APART!! You just might be too low on gas. 2 gallons is a splash!! Best, Paul A "Paul Asgeirsson" 31839... MORE
Rob... What year "B" ('68 emissions or pre '68 non-emissions) as to open or closed circuit fuel system. Cap'n. Bob '60 :{) PilotRob@... 31833... MORE

Bob, The 1500's have mechanical fuel pumos and the diaphram can get stuck if they sit to long and the gas dries out. You might take the top off and check before you replce it. Gerard "gerardchateau" 31825... MORE
Dear Listers, FWIW-Pictures of my MG obsession, McGee, are on my business site. Had too much difficulty with Yahoo to do it on the list site. If you're interested, go to the site www.webfootleisure.com, enter and click on the MG category on the bottom left. I'll leave the pix up till Friday when I turn on pay per click again. Can't h ave pool shoppers diverted with shots of my l lunacy! BTW-The car ran fine until the fuel pump gave up with less that 1500 miles on it. Decided it was a sign to get going on this... MORE
As regards flat or gloss, an old friend of mine visited the factory at Abingdon while they were producing rubber bumper cars and he said you could look down the rows of parked cars awaiting dispatch and pick out some that had distinctly more shiny bumpers than others, possibly due to different moulds being used. So it's your choice, but I think glossy looks better. However, the front and rears were actually different material, various sources say the rear is nylon (to resist fuel spills) and the front polycarbonate. This brings me to the point of this email -... MORE
I hope someone can give me some advice on this. Drivers school and race second weekend in June and I can't get the bloody running. I have a highly tuned (national level) race bugeye from the 70's era. Don't know the compression ratio, but probably pretty high, 12 to 1 at least. 4,000 to 7,000 rpm cam. 30 deg. advance. 110 octane race gas. champion n59g spark plugs. Electronic ignition box. No choke, just ram air intakes modifed hs2 carbs. Had it to a local brit car guru last fall and he tuned the carbs and set it up... MORE
Hi Ryan The heat shields are available new, I've just bought one for my car from my local MG spares supplier, Beech Hill garage! It's a pain to fit though, a real juggling act with the carbs.....why oh why are the carbs held on with nuts and bolts rather than having studs like an A series! Also it could be the petrol ageing the diaphragm, make you sure you buy top quality ones from a good supplier like Moss. I had three fuel Pumps go on my Beetle (bloody thing!) in 18 months due to this. James "James" 31721... MORE
This car is both my love and my worst enemy. '76 Midget, single ZS All cylinders firing, all new plugs this afternoon. She idles fine and smooth, but as soon as i hit the road she revs fine UNTIL about 2800rpm, same spot every time, the rev nearly stops. No matter how far i push the accelerator, it takes nearly 30 seconds to rev from 2800 to 3200, and that makes for a lousey drive. The manual choke is wide open. It looks to be getting enough fuel in that the fuel filter and the screen in the fuel... MORE
my 79 1500 was smelling like gas badly. Noticed the water controlled choke was basicaly hanging by one screw. So, like a fool, I disasembled the choke while I was in there, just to see if everything was ok. Now the stupid part: I'm not sure if I lost it, or if it was never there, but there's no heat mass. Now my question is, it's nice and warm here in NH now, being spring and all; Do I even need a choke, or can I just seal off the holes in the carb? and how hard is it... MORE
But the big boost will come from the Mata Fuel Injection. Bob, Troutdale, OR "Robert Webb" 31559... MORE
How I came to a Midget...? A few years ago, my brother gave me a 1975 FIAT X1/9. He was having some problems with it. I got those fixed. It was a fun little car. Like a go cart, but street legal. Well, one day I was driving around town and happened to look in the rear view mirror. All I saw was flames and smoke. Now, mind you, the only thing between me and the fire, was the gas tank. YIKES!! I thought to myself, "So this is how it's going to end. Riding a flaming FIAT into... MORE
Hi As a sideline to the techy questions and to satisfy my curiosity...... I was just wondering what stories there are about how you guys came to be so into Midgets. They don't really seem like the first choice of car for the wide open roads out there. (or have I seen too many movies!?) I know that America was the main market for MG's since the TC and that they have a huge following over there, but why a Midget as opposed to say a Mustang or a Camaro? I'd love to own a Mustang, but trouble is... MORE
Just want to say a big thanks to everyone who answered my post. As advised, I fitted a fuel pressure regulator yesterday. Early days yet, but it's purring like a kitten! It's never run so well. I was working on the car as I was thinking of selling it. It now runs the best it ever has and I'm starting to have doubts about selling it after all. I'm not sure I would ever have come up with this solution on my own. $21 and 20 minutes and it's a different car! Thanks again guys. Alan. "Alan Hearnshaw" 31486... MORE
Well after posting the message I cooled off and went back out and looked things over. I know that if the pistons open too quickly the engine will get a lot of fuel and not that much air. So I fiddle with the mixture nut and watched the piston when the throttle was opened. The pistons rose but the headers started to glow red! Argghh, I thought I'd timed the cam in better than that. Has anyone had a vernier cam gear slip on them? I don't remember a torque value on the securing screws, it's the Kent gear.... MORE
Hi Ben The stainless braided hoses look good, but my experience with braided hoses (fuel hose) is not positive. I find that the stainless braiding either eats it's way into the rubber hose and chews through it, or the rubber hose inside perishes without showing any visible problem. The first you know about it is when the pipe is dripping in petrol! Ok, oil pipe is thicker and probably under less tension/movement than a petrol pipe and it doesn't 'melt' like some cheap petrol pipes do with modern fuel. Even so I'd rather see the rubber pipe and be... MORE
Alan Hershaw....float level Bet you hit the nail on the head Alan, considering color of spark plugs under normal driving conditions. Too much fuel pressure can also be the gremlin. Webers (for the road) prefer about 1.5psi, but no more than 2.5psi even for highly tuned units. You MAY need a fuel pressure regulator? Cap'n. Bob '60 :{) PilotRob@... 31413... MORE
Ed.. 2 years isn't that long for the engine/ drivetrain though this will most likely not be so for the hydraulics. Have a portable FIREX standing by. Assuming the fuel pump is doing it's thing, add as much fresh gasoline as you can. Pull the plugs and using a healthy battery, turn over the motor until the oil pressure comes up. Do this in 5 second spurts over a period of time so as not to abuse the starter motor. Reinstall the plugs and fire it up, running initially gently. Good luck! :) Cap'n.

I use the valvemaster with octane booster and it certainly stops it pinking when using cheapest unleaded petrol. Terry "terry.isherwood" 31323... MORE
James, A couple of points about the fact that lead was not introduced untl mid-30's (and then ommitted again during the war years. The lead does 2 things; 1. It "lubricates" the valve stems. This only became necessary as finer tollerances were introduced and engines ran at higher revs. Not critical for many of the earlier side-valve engines. 2. It reduces pre-ignition. Again much less of a problem on early low-compression engines. I have run an old 750 side valve engine on a mix of petrol and paraffin (kerosene) It was common practice during war year rationing in the... MORE
Hi Ben Converting the head by fitting hardened valve seats is the only proper answer. I take the view that the worst that can happen by using unleaded is a valve buring out, in which case all that needs to be done is to have the hardened seats fitted at that point(and a new valve of course!) The additives are bad news as not only are they expensive but if the car is not used regularly it can form a gunge in the tank and clog up fuel pipes and jets etc. LRP hasn't been available where I live... MORE
James... Could not agree more with your take on "properly" going unleaded with respect to cylinder head, etc. I noted you were using "regular unleaded" before switching over to Shell Optimax. As I am in the USA we may be using the same words but with different meanings.... ...do I understand you to mean "regular" (as in low-octane unleaded) or "regular unleaded" as in "normally available at the corner pump" unleaded "hi-test" (aka "premium"). I think your gasoline is shown in RON at the pump "over there" while we utilize PON "over here". But adding about 3 numbers to... MORE
I'll be flying out to Newburg, NY this weekend to drive the MGB back. It's running well, so there should be no issues. In case there are some forseen issues, I would appreciate people who may live along the way that I can use as an emergency contact. I'll be taking I84 from Newburg to Scranton, PA, then I81 to I80. I'll be taking I80 to Acron, OH, I71 to Columbus, then I70 on in to Indianapolis. If you live on the route, or nearby, and don't mind, I'd love your phone number, which I promise to not pass... MORE
