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? |

Keeping you up to date:
This weekend I should receive a timing-light in the mail (with an advance dial). At that time I will attempt to check or reset the timing (8 deg at idle and 27 to 34 deg at 3500 rpm). Not yet sure how I'm gonna do this, as I had the fan powder coated last summer, but I should be able to find a way to mark the TDC. My Uncle (that raced his factory 914-6 in California) mentioned that I should install larger idle jets (0.65mm) to solve the idle problems. His thinking is that my cylinders displace almost 600cc and need more fuel to idle. Does that make sense to ya'll? |
