Check for vacuum leaks. I've had more than one motor that I was sure I
assembled right suck air from somewhere.

First I check vacuum lines, then I listen for telltale whistles while
the engine is running. If I can't locate something that way I'll use a
propane torch. I open the valve slightly and pass the nozzle around the
base of the carburetor or around the edges of the intake manifold where
it meets the heads. If you get the nozzle close to where a vacuum leak
is it sucks in the propane and the engine smooths out. Just remember,
you are using a flammable gas. Make sure you don't have a spark plug
wire arcing somewhere first and do it in a very well ventilated
area......like outside. There's no need to get too close to the
distributor. There's nothing there that would be a vacuum leak anyway

Spraying carburetor cleaner around the base of the carb and around the
intake manifold will achieve the same results but carb cleaner is one of
the best paint removers I've ever seen.
