Hoping someone can provide some advise on where to look to correct engine misfire problem.
Engine is ‘57 factory McCullogh supercharged 312, running the -C camshaft. Was recently assembled.
Here is what I have found so far.
Vacuum is steady but reading 15” at idle.
Initial timing 10BTDC.
Plugs all look good but possibly a little lean.
Checked for vacuum leaks with propane, no leaks found.
Cold valve lash in spec for -C cam intake .022 and Exhaust .027.
Teapot Holley Carburetor was rebuilt and run tested.
Cam was not degreed when installed, set at factory location.
Suggestions on where to look next are appreciated. Randy
