Re: still stalling

Check the vent to your fuel tank to make sure it's not clogged with spider webs or some other form of junk.<br /><br />A clogged fuel tank vent or fuel tank fitting can cause the type of problem you are having..<br /><br />Have you checked to see if your fuel pressure at the carb is in specs?<br /><br />Is your carb bowl float getting stuck in the down position?<br /><br />Maybe the needle and seat is not allowing enough fuel to enter the bowl..<br /><br />Any of the above items will allow you to cruise around real slow but stop you dead when you try to run at at high RPMs.<br /><br />Hope this helps you out some..<br /><br />PB
