recheck the valve lash if not recheck the camshaft make sure is for the engine you have or check your piston rings make sure they are not blown out or recheck the piston to make sure is for the right bock (engine) that you have
When you slide the cam out far enough to barely mesh the gears what you are doing is defeating the compression release mechanism.The purpose of the compression release is to make pull starting possible.Look at the compression release mechanism on the backside of the cam gear and all this will make more sense.Simply put nothing is wrong with your motor it is designed to do this.
@@travis48g yeah nothing was wrong with the motor, but the valve lash was set too tight and was holding the valves open... Basically, when I took the crankcase cover off, the cam was dropping ever so slightly, so the pushrods were dropping, and allowing the valves to actually close.... With the crankcase cover on, the cam would push up on the pushrods slightly, and cause the valves to hang open. A buddy of mine pointed it out the next day and after loosening the valve lash, it cranked right up first pull.
My problem is this motor for some reason doesn't have the inner lock nut not a outer locking nut it's just the bolt that holds the rocker arm in. First time seeing that myself.
These engines have a decompression lever that relieves the cylinder pressure when pull starting the engine. You can also check the cylinder pressure by loosening the lash on the exhaust valve to bypass the decompression lever. This will give a better reading
Yo buddy your video save me a lot of headache. My valve lash was way to tight.. play with the lash n now she good.

I ended up sending the video to a friend, and he suggested valve lash as well, which turned out to be the issue! Motor runs great now ...
@@Steelcrafted oh ok well that’s good
Value lash to tight no play

How u doing? Im having the same issue and was wondering if and how u fixed it if u did? Its driving me crazy man.
It turned out the valve lash was too tight and was keeping the valves open slightly at top dead center....
What did you set valves to? I have them set correctly with the Same issue and no adjustments have seemed to work.
I haven't yet, cause I can't find the specs on this particular motor
