Can someone PLEASE help me with this dilemma. Okay, so I just went through roughly 3 tanks of the 16:1 (8oz of oil to one gallon gas) ratio and just now put in 20:1 (6oz of oil to one gallon gas) and it ran fine for about four miles. Then it started to die out. I would pull in the clutch and rev the engine and it would rev. But then started to release the clutch and the motor would bog out. WHY?!!!
