Put on the new mini high torque starter double checked the timming put on a super coil. got plenty of spark now check all plugs. almost started. after we try to start it and leave it set for approx 2 min and try to start again, it starts for only a couple seconds. it will do this continually. going to change to a smaller carb to start with. what do you all think. could it be the fuel pump its new but only stock. thanks for the help!
