I found out the problem It was I had a two line system . one going to the carb and one plugged with a plug. What was happening was the engine would build pressure in the tank and quit and run rich !! When I would take the plug out or the fule line off the carb fuel would spit all over . So I un plugged the line and have run 3 tanks fully out with no problems and the plug was perfect!!
Thanks for your help !! I guess I was just thinking nitro being this was my first gas and didn't think about the pressure !! This engine runs great would recommend to any one !!I thought I was kinda werd it had pressure in the tank !!

Thanks,Josh
