After many delays, the head is decked and repainted, and the block surface has been cleaned. New head gasket, sprayed with copper coat. The head went on with few problems. Torqued it to spec in three phases, and put everything back together.


Finally fired it up today, and it ran just like it did before the head gasket replacement, and if anything it coughed out MORE white smoke than it did before. Ran it up to temperature, shut it down, and retorqued the head. Took 3-4 pulls per nut to do so. Now it won't even start. Gave up in disgust and put the charger on the battery.


Is it possible the choke and idle mixture are way too rich, thus instaflooding it? Newly cleaned spark plug came out black after we shut down. It has fire, but it seems weak. Won't even hit a lick on starting fluid. Any ideas?
