I’m working on my Kawasaki FR651V on a cub rzt50
It would start and run fine for about 10 minutes then die; I have 2 of these mowers (other one runs fine) so I swapped carbs; new fuel pump, new fuel filter, finally I found the problem it was the line going from pump to crankcase had a small nick in it. That was short lived lol. Put it back together ram for about 10 minutes and then it died but this time upon re-firing it has a hard time getting idled up then once pto engaged it backfires pops etc; spark on both cylinders, CYL1 doesn’t change a thing once unplugged. CYL2 unplugged kills it, pulled valve covers on 1- lashing is correct and no bent pushrods; kind of at a loss with this thing anyone have any ideas?
