David - Getting the pumps spec'd would be fine if we didnt have to alter the pressures during rolling road tuning, so kind of eliminates the ability to fine tune the fuel system every time - which makes it expensive if you have to redo the pumps every time. I put a heat shield on the car some years ago and find it to be of no use against heat soak when the car is not moving. I'm the 3rd owner of a MG Midget. If the engine starts when cold, and after a few miles of driving, the engine loses power and stops, then it sounds that the carb float bowls were initially full of fuel, and were not being filled by the fuel pump during driving. Got one to sell? The factory had a heat shield for the fuel line for some cars along the firewall that is often missing.

MGOC is a privately owned commercial business. The article discusses in details what happens in a cylinder after a plug fires and how turbulence in the head is critical in spreading the burn. Fit a quality low temperature thermostat, say, 74C. Turns out everything in the engine bay was at that temperature, and of course it would be - there's a great big radiator at the front heating everything up. Unscrew the diaphragm one sixth of a turn at a time in the same manner, slowly pressing and turning until the "throw-over" just operates. Can anyone guarantee their loyalty to the Crown? Greater wear protection Greatly extends oil drain intervals.

It is not particularly relevant to the above as it isn't near either end of the boiling point range. For all it means there is a real issue and it is reasonable to implement solutions that go further than implemented by the factory. A better solution to prevent gasoline break-down during storage Safe to use in all grades of gasoline and in all 2 and 4 cycle engines. Not legal for sale or use on California pollution-controlled motor vehicles.
Description: Ultimate protection against Ethanol blended fuels. Toluene - is not an oxygenate! In short I'm not sure that modern fuel makes a huge difference in running temperature given appropriate ignition timing , but alcohol sure does cause fuel boiling with conditions of low fuel flow an low vehicle speed or short term parking. The water filled tubes transmit the heat to the fins, which transmit and radiate it to the air. As far as rebuilding SU carbs is concerned, we have an informative video tape on the subject, parts, manuals, or complete rebuilt carb sets if you're so inclined.
