Lean MisFire

[Mercmarc]

Hello Crankster,

Good point on all the carb circuits. Lets not ignore the choke circuit. I get choked up about that one. Just keeping it light. :-)

Unfortunately I do not have access to a Wideband and yes that would take some of the guess work out of AFR numbers.

Elevation of Roseville Ca is 161 ft above sea level.

Camshaft is a 274 lift and duration.

I will install Charlie ny distributor when it arrives and keep everyone posted on the electrical side of things. Then turn to the carb questions once again. Solve or eliminate one thing at time. As mentioned before, I have run two electronic distributors and one ford load a matic with absolutely no change in driving performance on this engine.

With the engine being new from H&H I am not going to second guess Mikes work. Under load the engine runs strong, and the engine idles with a slight attitude per Mikes original set up with these carbs. The lean misfire surfaced once the engine was in the car and driveable.

Please stay tuned

Respectfully

Marc
