I recently rebuilt my carb because it wouldn't idle. Today I went to start it and it wouldn't start. I have taken the carb off and cleaned it many times. I have even tryed using starter fluid but nothing seems to work. The only time it will start is if I let it sit for about 2 hours and then it will kick over run for about 2 seconds and then just die. After taking the carb off for about the 6th time I got it to stay running for about 15 seconds. I really don't know what is wrong. At this point I'm about ready to give up. If anybody has had this same problem please let me know what you did to fix it. Thanks
