Now that the milder 2056 is in the car, I could use some advice on carb tune.
compression is at 8.8:1, valves are 44/38, cam is Webcam 86a. Weber IDF 40's have 37mm venturis, 135 mains airjets 200 F11 emulsion tube I am told by the builder that I should step down to 34 venturis, but, have no idea where else to start. Car will go to a good tuner soon enough, just want o have a good starting point. |

Hijack:
On my 2056, I have some popping when the engine is pre-warm. No popping after warmed up. If I run anything less than 93 octane, I get a lot of popping. Carb settings: Weber IDF 40 28mm venturis, 115 mains Idle Jets: 50 airjets 200 F11 emulsion tube Recently adjusted valves (didn't change anything) No vacuum leaks. No info on cam or valves. (2L heads) Suggestions for adjustment? |
