This is a motor that I got at a flea market that I have been tinkering with.I rebuilt carb and added a new impeller.i have had it 2 or 3 years .It has not been run .The compression cold is 90 on the bottom cylinder and 100 on the top .Is this ok.I assume it will go up warm and I'm not sure if my compression tester is calibrated.Also when you tighten the recoil start it will lock it down all parts appear to be in place What will cause this.I do have the manuel for this motor
