I had a similar problem that was caused by a worn Distributor. This
was after rebuilding the engine (spun a main bearing) and changing the
carbs to webers. It still ran rough and ran a bit warm. After I changed
the distributor with a rebuilt one the engine ran 10 times better. I
would recommend borrowing a buddies distributor to test with.
