Harbor Freight Predator 212 Has No Compression! Valve lash too tight!

This Predator 212 engine has zero compression when the crankcase cover is on. Without the cover on, i get great compression. No clue what's wrong.

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.

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

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 ...

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.

[@Steelcrafted]

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

[@craigmoudy7847]

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.
