Comp cams CL20-246-4 solid lifter cam. Been in it for 4 years with no problems.
Tomorrow after work I plan on removing idle mix screws and blowing them out. I will also take distributor out and inspect.
Gasket @ choke housing for leaks

Steve ...I was referring to the choke housing to carb body gasket for the leaks....just confirming.
