I have built many, many, of these 49cc Chinese 2 stroke kits.....So I'm no newbie...I built one a few weeks ago and test rode it several miles and it worked fine....It set under my shed for about 3 weeks and then it simply would NOT start...The plug was firing, I replaced with a new carb and still no work..My very heathly son could pedal the bike with the clutch engaged, but with some effort.....Today, I pulled the engine apart thinking I would find a broken ring causing low comression..(Have no gauge)...the rings were fine, the cylinder was not scarred at all.....however, since I had an extra set of rings I replaced them.....reassembled the eninge, added a bit of gas to the tank, weather temp. was about 15 degrees warmer, and the engine started with one choking....so actually I did nothing to the engine.....could the old rings, (they were new) have been the problem?????I'm at a loss.
