Ok My B2200 I believe has some carb issues. It will run like a champ till I hit 2500 rpms, at that point it will surge and hesitate violently but if you just push the throttle past that point it runs like a champ again. We have already replaced the distributor cap and plugs and that hasnt made any difference. Is there any known carb issues with these machines? Thanks guys.
One last thing, it will also only do this in gear. If I have it in neutral and rev it, it will not hesitate at all but the moment I put it in gear and get moving to that RPM it will jerk and buck.
