Hello,
Not having much luck with the Search function. The car: 1972, with 103mm cylinders (2.3l), aftermarket cam and larger valves with double springs. Fuel supply: Dual EMPI HPMX 44 Carburetors, Jets: .55 Idle, 1.55 main, Air 1.75. History: After car-fire engine was out, heads taken off and some studs and springs replaced. Changed to quieter exhaust. Had trouble with dialing in the carburetors and changed the jets to the recommendations from EMPI (see above). It runs a lot better now. Remaining complaint; The car runs pretty good (especially above 2,800) RPM. However; It takes me a while to leave after each stop (stop signs traffic lights etc) because the car want to stall. When I push the accelerator to quickly the RPM dips down, and car will die. Only when I ease on the paddle very gently, it will increase in RPM, and I can lift clutch at above 1,500 RPM. Anyone here understands this issue? |

Hi Hans,
everyone is going to have an idea about what your problem is, myself included(accelerator adjustment)but you really need to educate yourself and learn how to fix it yourself. Most mechanic nowadays are simply parts replacers, not diagnosing and problem solvers. Buy the book, read it and understand it, then adjust stuff. Make small adjustments, try it out between each adjustment. Its a great feeling when you figure it out yourself. I'm not sure about the hpmx book, but I have the dellorto which is very much the same, and it has a section that says "if it does this then try this and this". that helped me immensely! good luck blair |
