I have a GX390 that was left outside. Water leaked into the crankcase from two missing bolts on the exhaust header. It was seized. I flushed out the crankcase and gas tank, rebuilt the carb and it started fine and ran fine in my shop.
I took it out to use it and it won't start. I have had the head off a few times and reset valve clearances. I have spark. With the recoil off, I hand spin the flywheel. I get a spark when the piston is at tdb. I know it should be firing at tdc. Is the timing on these engines that far in advance?
