new here and i have a brand new monster gt 8.0 i fired it up for the first time and it wouldnt run at first then when it finally did fire it went crazy like it had an air leak and i had to pull the fuel line.... so i took the carb off and cleaned it and the fuel lines with nitro cleaner and compressed air and the i cleaned the tank with mineral spirits and i started it and got it to idle for a sec then it died,so i tryed again and the same results until the motor got warm then it went crazy again like it had an air leak ????????I've followed the manual on the carb setting and put a brand new glow plug in it so idk i hope u guys can give me some ideas
