I just recently puchased this motor and I initially went to start it this weekend. After some time it did light up, and I ran it for 30 min in a test barrel and shifted in and out of gear. Then the next day I wnet to start it and it lit right up but after running for a min it stopped and now I cannot get it to start. I have checked the neutral switch , saftey swith, spark to the plugs and seems like I am getting some gas. Any Ideas, thanks
