Quite low. Try a different gauge.

125-135 would be good, .....10% between them would be a max difference and still be ok.

What is the best proceedure for a compression check? some say to warm it up, then put oil in the cylinders, Some say do it dry, what is the best?

do it dry not with oil as it will not give acurate reading

Don't use oil.
Remove all three plugs, hold the throttle wide open and pull about 4-5 times. Lower than 120 on a accurate tester would be low for that engine.
