I posted about the Inline 6cyl that woouldn't run past 1800RPM. <br /><br />I rebuilt the fuel pump and now the thing is really running bad. I think it's an unrelated problem. It won't rev up and it misses and smokes really bad (loading up on fuel). I disconected the spark plug wires one at a time and when I did that, it didn't make a difference until I pulled number 4 and then the motor killed. It has spark on all cylinder with a spark checker and good compression. Am I dealing with a weak spark issue or what? Also gas is leaking out of the carbs (most likely because it's not being burned by the engine).<br /><br />Please Help!!!!!!!!!!
