Re: OOPS I need some good advice here
that carb is toast, however a friend of mine has that same motor that friday he blew a piston,saturday he bought a used F250 and later this evening he his gonna mount it and would most likly sell you any part you need.
he is gonna part out the old engine.PM some time.
doesnt look like a half arse job, looks like someone let it sit with fuel in the carbs, thats what that nasty stuff is, fuel residue, could also be coming from the tank if you have introduced it to ethanol fuels in the past year.
