I just purchased the ATV and it run really rough with the breather filter on and lid on the breather box. Once I take the lid off and remove the filter it runs better but it backfires through the carb.
What could I do to fix this.
The carb is fairly new.
And I put high grade non ethanol gas in it hoping it would help some.
