my second build has been running beautifuly for 5 months. it now has no power at all, it lost all power in a small 15 minute trip into town. it will get up to speed on a flat road but as soon as the slightest hill comes along i slow down so much that if i dont pedal it will stall. havent changed anything on it exept the stock plug and lead when i 1st built it.... i am so confused as to what is going on with it. i tried running a little leaner. all that did was heat the engine up faster, so i tried running richer and it still has no power. time for a new build or can u guys fix it? ps its not compression .. she has plenty of that.
