Hello members, Ran into an issue with my 127 . Its been strong and faithfull thru the winter hauling firewood trailer. Sat since needed in my garage. Went to start, cranks and puffs a bit but wont catch. Tried new plug, gas.ect. Only sat for 4 weeks. Oil is clean, finally took compression, 50 lbs max. Thought of a valve hanging open. Soaked entire too end in marvel. Let it sit for 1 week. Cleaned out the cylinder and took compression,same 50. Added oil into cylinder,went up to 90. I did get it to start on that with gas in the plug hole. Ran supper rough, coughing thru carb,flames, couldnt get it to stay running. Took compression again ,back to 50 lbs. Im looking at piston/rings but wanted to ask you guys if I might have something else going on that Im not aware of. Cam timing or flywheel timing,something that might have let go . I have owned and used this for 5 years and its been the most dependable of all my yard tools. Thanks for any help. Cubs for ever !!!!
