Hello everyone, I recently put together a 49cc 4 stroke kit I bought online and after about an hour of off and on use the clutch exploded. After buying a new clutch I put it in and after a few more minutes of riding the engine started running REALLY rough. I left it in the shop for a day and when I went to work on it I noticed that the engine would not budge with the pull string. So I took the starting assembly off the front and used a bar of steel to turn the engine until it "broke loose" I tried starting it afterwards and it ran for a few seconds and subsequent times starting it have resulted in a REALLY rough idle for a few seconds. Any thoughts on what could have happened? And yes, it does have oil in it. Thank you in advance for the help
