you need a compression test gauge to check it.
I bought a cheap test kit i've used for many years for about 30 bucks.
120 to 145psi is good, but really you want all of them to be within 10% of each other.
So a reading of 110, 115, 112, 103 would all be acceptable.
But the lowest compression i've seen in a running engine was about 85.
You don't a chain, the cam gear is in direct contact with the crank gear.
You said you're rockers are moving so we'll assume the cam timing is ok.
A engine needs 3 things to run
and spark at the correct time.
How did you verify that you have spark?
