Crosbyman,
Thanks for the great info. Never noticed it in the manual. I will take the carb off and check that it is clean in that area.
Wires were replaced last year. I had spark on both cylinders jumping a 1/4 ” gap tester a couple of days ago. I will try to get a compression reading. Difficult to get an accurate compression test as the stand is shaky and motor is manual start. Compression was top 94, bottom 89 in October 2019 with very little running since then.
Apprecate your advice.

Edit correction – compression readings in Ocotber 2019 were top 94, bottom 89.
