It's my Camshaft buddy.

If the lower (intake) valve rocker is not then you got a serious problem. This would explain why you can't get pass the top of compression stroke with a lot effort as you are fighting the engine full compression.

Being an Intek single cylinder engine the lower push rod is like broken or severely worn. Another possible is a camshaft lobe problem but I have intake lobes worn that much.

Or it can be that rocker adjustment is that far off and the valve stem cap has fallen off. Also check the rocker stud to see it simply came loose and back out that much.

The valve clearances normally .003-.005 Intake and .005-.007 Exhaust.

Otherwords start with checking the easy to get to valve train components before opening the crankcase. As it might there instead of internal problem.

When come intake camshaft problems it can any from ACR broken, worn or loose lobe, to major damage of multiple components.

What would happen if the stem on the exhaust valve dropped inside?

The stem dropped

The stem dropped

Did the valve put a hole in the top of the piston. Did it damage the valve, valve seat, or valve guide.

Did it
