I just got the engine today an

I just got the engine today and this seems strange. I removed the Clyinder Head Assy. Now when slowly turning the flywheel near TDC - I get this wierd clunk like there are bad rod bearings. It is just maybe a 20 degree range of the flywheel to notice this. It does it on both pistons? Help? Is it scrap?

"Update: I just talked with previous owner and he told me it ran nice and quiet - no knock. f I had pressure on the prop it doesn't do it so I guess I will proceed with tuning it up.. aw,, yes!"

"after thinking on that awhile...i have heard that sev times too.....i believe,what that is,is a slight play in crank bearings,...as u approach TDC,the magent on flywheel is very close/over the coil,and tends to pull it...hence a slight..thump....."
