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? |

The nice part about carbs, at least our Weber's, is you can do these changes without opening up the carbs, so you could have a larger setup for racing, and a smaller setup for around town normal driving....swap takes minutes
