Botched Edelbrock 1407 rebuild?

[Geff McCarthy]

Thanks!Vacuum about 11 from the small orifice on front of carb. 10deg per the book! Will try both vacuum and check. Too much rain here in PDX today. !
And is the fuel level ok? Can too high affect the fuel/air mix?

Too high=rich
Too low=lean.

D. Vizard claims that a 0.100" change in fuel level [ not float level ] is about one jet size.

I think you start a new thread, & give a FULL description of the engine/history of the problems etc. Then better able to help you.

 

[Geff McCarthy]

Thanks,will recap in new thread. Today set timing 14 deg, perhaps idle a bit smoother, still backfires and quits. Note steam out rt side only. (no x pipe). Does that mean one bank rich or lean, and corresponding side of carb is mis-set?

Do you have a temp gun to see what the side to side temps are doing?

 

[Geff McCarthy]

i do! Will check.

If it is steam: suspect a crack or leaking head gasket that is letting coolant into the chamber. Would expect low coolant level in the rad. This scenario also ties in the symptoms.
I doubt that it is steam from condensation [which is normal ] because you would expect it from both exh pipes.
