the 216 is running real rich,if I let it idle for very long,5 to 10 minutes(I was flushing out my radiator)it wants to load up real bad,plus cruising down the road I can smell the fumes pretty good(I'm run'n 1 3/4 inch strait pipe from the manifold to just in front of the rear tire) I do need an intake gasket and have a small exhaust leak at the manifold/exhaust pipe connection(those will be fixed when the gasket gets here),another thing is my plugs,I'm run'n r-44t plugs in it,does anything I have listed cause a rich running motor or is it just a bad rebuild on the old rochester?
