Default Re: Engine Sputter

Yea, I changed the wire and cap. Used 7mm wire. I tried all settings on the carb needle and then just replaced the whole carb. It still does not run like it did the first week after assembly. I will replace the exhaust gasket this weekend and let you know if that improved the running. Seems if there are no reeds, the blown gasket may effect vacuum and cause problems. Since two different carbs did the same, I think I have eliminated that as the cause. I shut the fuel valve off while riding and once it started running out of gas (leaned up) the sputter went away.
