You may now have to re jet the carb and try dropping the needle to lean it a bit! now that you changed your mix ratio there is more fuel available or it's richer so you may have to lean it out some!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?!!!
i agree yeah most likely needle was thinking it had worked before carb hasnt been set up u need more air per fuel 1 notch higher on needle drops it down restricting flow of fuel more leaning out your mixture in midrange throttleYou may now have to re jet the carb and try dropping the needle to lean it a bit! now that you changed your mix ratio there is more fuel available or it's richer so you may have to lean it out some!
