Bought XT used...was running fine with fuel that was left in it. I mixed 25:1 and it started no problem. I couldnt drive much because of battery cover missing. So a couple days later i tried to start and got nothing. Took it to a friend we pulled the plug and didnt see spark so we ordered an ignition coil. Coil arrived we put it in started on first pull. Took it home it started easilt when i got home.. again didnt run it long. Yesterday after making a battery cover out of cardboard, i took it to the park. Pulled it out and no pop at at all...needles are set to factory..my mixture is 25:1. The guy who had it just told me he ran 32:1. Will that difference prevent starting?
