Now that it is getting warmer out I seem to have the following problem with my MG. When the tempeture is in the low 80's the car will run rough, stumble on acceleration after I have sat at a light fo
I understand that the plastic spacers serve to insulate the SU carbs from transfer of engine heat. Could the problem, or part of the problem be that there needs to be an insulative barrier between th
A series of ideas that may help, in random order, some of them gleaned from my experience with my similarly equipped '77. Idea 1: Get a better heat shield. A cookie sheet is okay, but you're going t
Am I just lucky or what? Yellow Fever has a weber and header and I have not had any problems with heat (yet?) The header is right out of the box, no coating and no heat shield. Am I asking for an hea
I swed you a word of caution in using a computer case fan for this purpose. Those little fans are not made for that kind of heat, plus they are not sealed for use around such level of moisture. I am
A good point. Go find a clapped-out Fiat X-1/9 at a parts yard, you can get the fan, a thermostatic switch, ducting and relays from that (the X-1/9 had a small fan that blew air on the carb when a te
Datsun F310 had the similar fan setup. I think that some Chrysler products had carb fans, not sure which ones. Paul A /// unsubscribe/change address requests to majordomo@autox.team.net or try /// ht
There are a number of issues here. The biggest problem is the air temperature under the bonnet. A secondary problem is the temperature of the fuel. Using a fan to blow more air under the bonnet isn't
Dear RS, I've never heard this fact before about jet-hot coating, could you expand on this? The header on my Sprite was jet-hot coated back in '93 and has been on and off several times without any si

I had an article on my site several years ago about installing wing vents to help move the hot air out from the engine compartment. I'll see if I can dig it up from the "Midget Web Archives" when I g
I'm quoting from a book rather than talkin from first hand experience. The book is: How to PowerTune MGB 4-cylinder engines by Peter Burgess. Seems I misquoted because he talks about exhaust wrap cau
One big diffedrence is that JetHot coating goes on the inside of the manifold and keeps the heat in the exhaust gas and out of the metal on the other side of the coating. Header wrap keeps the heat i
I don't know if this is true or not. I have heard that fans located on both sides of the engine facing down, pulling air out of the engine compartment has a tremendous effect. The aerodynamics of the

Bill, I will bring a couple of asbestos shingles with me. glue or screw one of these to the wife's finest cookie sheet and lets see what happens. Just be warned, it is asbestos, the deadly kind wear
When I had my '78 1500, it had original equipment of a polished steel heat shield and then a second one made of some sort of asbestos - like material. Guy -- Original Message -- From "Frank Clarici"
My '79 doesn't overheat either. It seldom rises much above the lower mark. I had a hotter thermostat to get the thing to heat up to optimum temps. I also have a Weber (DVG) and a header right out of
