Re: Emulsion tube quest
Is the engine at cruise [ where it is rich ]......running on the idle cct...or main cct? That is why I suggested earlier in this thread to remove the Etube assemblies...& drive the car. If you can reach your cruising rpm, then obviously the engine is cruising on the idle cct. If it is still rich...

Re: Emulsion tube quest
If you plug the progression hole above the t/blades, that will make it richer, not leaner.

Re: Emulsion tube quest
Another thing. I never liked the Weber spring loaded STEEL needle & seats. Carbs hanging off the side of an inline engine are subjected to vibration/movement. Not good for maintaining a stable fuel level. Redline in Hollywood, California sell Viton needle & seats for Webers. Might be worth g...

Re: Emulsion tube quest
[1] One or two carbs on the engine? [2] Agree with others that chokes are too big. Big-ger choke does NOT automatically translate to more HP. [3] With such big carbs, only small throttle opening required for cruising. Are you cruising on the idle cct or main cct? Try this: remove the m/jet, E tube &...

Re: Emulsion tube quest
Another combo you can try: smaller main jets, maybe 160 or 165 with 140 or smaller AC jets.

Re: Emulsion tube quest
Have you tried bigger air correctors 180-200?
With the bigger AC jets, try the F7 E tubes.
Or F16 E tubes.

Re: Question for Tuner
A member has kindly sent me the Fed Mogul manual, which describes this hole. It is an air bleed, purpose of which is to smooth the transition from the low to the high speed cct & improve part throttle economy.

Re: Question for Tuner
I am not sure, have not seen those on Holley carbs. Add more air? The holes I am talking about are on the underside of the booster.

Question for Tuner
Tuner. Referring to the Carter AVS carbs that were used on Chrys engines from 1968 to 1971. Specifically, the primary venturiis which are secured with two screws. What I call the 'bridge': the section or arm that connects the main body to the booster ring. I have seen some where there is a hole dril...

Re: Flat Tappet cams & lifters

Re: LS cruise timing
Are they not known for a very efficient chamber design? If so, that means less timing under all conditions.
