I opened up the front of the engine today, I wanted to check the timing chain, thought maybe it jumped, check the timing on it again, all good, eccentric was tight and inplace, did find the balancer seal was bad, and the water pump had over a 1/4 of space between impeller and back plate, also found the round gromment that goes around between the back plate and timing cover was out of place. Tomorrow I'm gonna set the ignition timing and replace the tsat and if problem continues I'm gonna look at the radiator. I understand about the fuel filter and no fuel in it, it is also glass, what do you recommend for a good filter?
