I finished rebuilding an old H50 engine. It's running great now and starts on first or second pull but have one concern. Every time usually on first pull when you pull to start it will snap back really hard, then next pull will be fine and it will start and run great.
I noticed when I was done the rebuild I couldn't turn the crank by hand, had to put flywheel on to turn and was still really tight. Put oil on all moving parts before closing case. Watched everything move and looked fine. Since this was my first rebuild I figured it was suppose to be tight and new parts had to seat it and loosen up?
All bolts torqued to factory spec.
These are all the new parts I put in:
piston & rings "standard" (honed cyl, still within spec 2.6250), connecting rod, valves (lapped), valve springs & lifters, breather kit w/green filter, OEM carb, all new oil seals & gaskets, points & condenser, spark plug
Engine seems like it is getting a little looser to pull start but still snaps back almost breaking my arm!
Appreciate the help
Thanks
