Ok well it sounds like you have a recipe for disaster there if you are
noticing fuel coming out of the exhaust manifold. It also sounds like your
sprk plugs are probably really fouled. Remove the plugs disconnect ignition
system and crank the engine over. You need to get rid of all that excess
fuel in the combustion chambers. After you have done that clean all the gas
off of the engine. Then put a new set of plugs in there and attempt to start
it with the fuel pump disconnected. this will burn any residual fuel left
over from the cranking. after it is all done burning excess fuel then hook
the pump up. if it doesnt fire right up then you will have to readjust your
fuel mixture. I dont know how much you cranked that allen but anything more
than one turn and you have put it way out of adjustment. if thats the case
then you will have to crank the allen counterclockwise in order to lean the
mixture out until you get a little action. HTH
