Morning, Mr. Fornal! It's 28 degrees in Stamford, CT; wish I was in Texas!! Agree on current Lucas "cheapo" stuff though I believe Peter C. of nosimports carries the "quality" replacement stuff, assuming such "quality" supply is available. I was having a problem with rotors "splitting" as they could not handle electrical potential of PerTronix if plug gaps opened beyond .028. Peter sent me several of his "quality" rotors. Found these much more "heavily constructed and am able to run .032 gaps with no problems in current stock 1098 "A" Series. Your remedy makes good sense, otherwise. I think... MORE
Tad, I haven't gotten around to calling them yet. I have been extremely busy with family, the holidays and such. I was hoping to get in touch with them last week, but now it doesn't look like I will get a chance until maybe next week. Relatives coming down out of the snow for a visit. I did manage to get the engine all apart. I was really suprised. The bearings and all journals are like new. They mic out to new specs. The honing marks are still visible in the cylinders. The only thing I could find was... MORE
Spot on looks as though the engine vaccum was sucking open the butterflies against the internal carb spring. Now I have adjusted the limkage to make sure that the throttle springs are under tension at closed all is well with regards this. Problems now seem to be centered on leaking exhaust ( pulled apart for the second time) and the rev counter a new one (elliott 10k) which seems to be over reading and undamped. On the bright side all the fluids have stayed in with the car run fully up to temp and when you give it some... MORE
Not a problem at all, Mike, though it sounds like one, doesn't it? Remove all linkages from your Weber, start your engine and marvel that the engine finds it's own idle depending upon vacuum and condition! Cool! (No, I am truly "not knowing" the real scientific reasoning behind this phenomena but, mine used to do the same thing, sans linkages! Evidently, perfecty normal!! Scared the hell out of me at first though; thought something definitely wrong!) Cap'n. Bob '61 :{) PilotRob@... 6742... MORE
As far as to what was causing your sudden loss of oil pressure, I can only offer a few guesses as to the etiology. First of all, it is a positive displacement gear pump. These pumps are manufactured to very small tolerances and it is rare that they fail all at once. As the tolerances in any highly machined apparatus become larger due to wear, they tend to become less and less effecient, therefore, I would suggest the probability of a caststrophic failure of either the shaft or the key that holds one of the gears on that shaft....

Divide the bore by 2, square it, multiply by 'pi', multiply by # of cylinders, take away the number you first thought of!...I made the last bit up!!! Dave "daveo138" 6713... MORE
Merry Christmas all. I quick question because I am having a bad case of brain fade. Knowing the bore and stroke of an engine how do you compute the size of the engine. Thanks Doug 77 "dougple" 6712... MORE
After 12 months work I have today fired up my Midget sounded great now need to insure and tax. Only problem is that it is reving 2000+ with no throttle linkage conected and tick over adjustment screw taken completely out. Must be problem inside carb any ideas. (My wife has said if she sees me in garage tomorrow I will die. Spoil sport) Spec is 1380cc DCOE 45 carb ( this was second hand and I fitted service kit and re jetted.) "Peter Whittle" 6698... MORE
Pete Whittle- BTDT - You do not have a problem, at all. This is quite normal without throttle linkage attached, though I really do not know the reason for it but this will occur with "fixed venturi" carbs. (Not a bad idea anyway - helps to break in cam properly). Once you have attached and adjusted the throttle linkage, "problem" will disappear altogether. Incidentally, the "healthier" the engine is, the higher this "idle" will be. Must have something to do with vacuum and good "seal" in combustion chamber; I am truly "not knowing" reason! Cap'n.

I am replacing the head on our 1990 Plymouth Colt and Mike measured the 1.5 engine while we had the head off. It is 18" long, compared to the 20" that the 1275 is. Do any of you know if the Mitsubishi 1.5 is used in a rear wheel drive application, especially with a 5 speed? Oh, please don't tell Frank I was asking this question...................... TIA, Brad Brad Fornal 6706... MORE
Redoing the cooling system on my bugeye with a 1098 engine. Am replacing the thermostat and also putting on a new thermostat housing (the old one disintegrated when I took of the radiator hose. The problem is that I can't seem to get the old housing off. Looks like it should come off easily, but it won't budge. I have tried prying with a crowbar, banging with a hammer and even a little with a chisel where the gasket is all with no luck. Anyone have any tricks for getting this off, or do I just need to apply... MORE
The middle stay rod is there to keep the rag top from ripping the frame off the top of the glass. The bottom center end of the stay rod is also a mount to keep the frame down on the body work. Remove the rod,,, leave the roof up.. and do some highway driving for about a month...or 500 miles (which ever comes first) and watch the frame lift of the top edge of the glass!

Hi Sam. Yes I know of one. If you e mail me off list (I think you should have it from before) with your phone no. and I'll give you a ring Sunday night.(as I'm off to have lunch aboard "The Flying Scotsman" today. How cool is that?) Maybe also we can have a chat about our "mutual friend". Gary L Camden, London 58 Frogeye Sorry Just realised I have your phone no. Will call you Sunday "garyloisuk" 6682... MORE
Correct me if I am wrong, but I believe that the oil pump on a 1500, is a cam driven diaphragm pump. It would seem strange to hear that a pump of this type to lose it's prime condsidering it's location. The diaphragm is nothing but a thin sheet of metal only a couple of thousandths of an inch thick. Held it its housing around the perimeter, a plunger is attached to the center. As the cam lobe presses on the cam follower the plunger rod is moved back and forth, thus flexing the diaphragm back and forth, around... MORE
Brent- Have been reading postings from guys with 1500's regarding comments on bearings and oil pumps, etc., with engines approaching 50-60K. Interesting. Incidentally, when I was younger and running tuned and even stock Series A engines, I religously changed rod bearings at 25K and checked the center main as well. Back then I used to keep the revs up and we didn't have synthetics. Today my driving style is all about smoothness and the engine(s) very rarely see more than 4.5K with better filters and oil at that. Only once had an oil pump begin to go and replaced... MORE
I'm completing a rebuilding of my Bugeye's cooling system and came to a dilemma when replacing the thermostat housing. I'm almost positive that I have a 1098 engine. This would mean that the correct thermostat housing is one with a rounded top. However, the one that is on the engine (which broke off in my hand when I removed the radiator hose) has a flat top like originally came on the 948 engine. It looks like the one with the rounded top might provide a little more coolant flow. Does it really matter which one I use? Thanks Bob... MORE
Roger I rebuilt my 1500 at just about 50K miles. Oil pressure was not real bad but because I did some damage to a piston and head I rebuilt the whole thing. Some of the rod and main bearings showed quite a bit of wear, down to the copper stuff. I don't know how much longer it would have lasted but probably not very long. I purchased the car with 47K. The PO told me it was rebuilt awhile back but I doubt it by the looks of the bearings. The cyclinder walls were also out of round. What... MORE
Roger, the power plant currently has 55,720 miles. I had heard the same things, so when I bought it (@ 54,000) and I was doing a lot of out of town work, I paid a "specialist" to inspect the engine, and renew the lower end. I was billed for the inspection, new bearings, pump, and gaskets. Now I wonder cause he also billed me to replace the ignition switch that failed four days later. When I removed the old original switch, he said oh well. I will report any findings I find. "Brent Wolf" 6651... MORE

Not to worry. She is on her way to being fully open. Just can't understand what would have caused it. I will let you know what I find. Bearings?, pump? Oil galleries? Lots to look at. "Brent Wolf" 6647... MORE
Brent: Do not drive the car any further! Stop! You can only add to damage which at this point, may be easily "fixable". Don't want (possibly) metal wondering around in there any more than it may already have. Something "broke". Nothing you did, obviously, but something just "failed". (or came loose). Problem is oil pressure "suddenly" coming up slowly. Pressure is to bearings. Something clogging oil galleries? Something in the "way" of oil getting to "pressure" point(s). Bearing surface gone bad, ("catastropic fail")? No choice: "open" it up. See what's in the pan, to begin with. RATS!! Cap'n. Bob... MORE
Dave C.'s "Crane" message: Also used a 700 and 3000 Crane set-up in a Vizard tuned 1275 (about 105hp) application for 10 years: never a problem, ever, Rich. Excellent units, either one. Went to PerTronix only to "simplify" set-up (self enclosed). Cap'n. Bob '61 :{) PilotRob@... 6616... MORE
Richard, Went to your web site. Your 76 is the duplicate of mine. I noticed your wish list, one comment. When I was restoring mine, and looking into the seat bottom webbing, I was told to get the seat bottom for an MGB. It is one solid piece, not a series of strips. It takes a little extra effort to get the clips on, but it is well worth it. The support is much greater. I don't know about VB, but I called M*ss and described what I wanted, they had it. No your oil pressure. Don't really know... MORE
Rich, Oil pressure good - little oil in rocker area is a good thing; indicates nice tight rocker set-up. Two have nothing to do with each other anyway so no worries here. Have used Ignitor on 1098 and 1275's for years. Had problem with first installation regarding a too short wire which rubbed on the distributor plate (on which the Ignitor was mounted) and chaffed through to "short" on the plate. Cut back plate to give more clearance and have not had a problem since (many years of service). Early PerTronix units had their problems with reliability. Have not... MORE
Has anyone had any experience with a conversion using the Pertronix Igniter on a 1500 Midget 76' Non Catalyst? Some pros and cons if any. Just got the car running after 5years of sitting in the garage. I noticed that when I remove the oil fill cap while the engine is running, there doesn't seem to be a lot of oil flowing thru. Oil pressure is up. Is that right??? Thanks, Rich http://home.att.net/~sagredo/mg.htm "Richard Sagredo" 6612... MORE
