Something isn't right. I put a new carb on this HM80. It will run if I screw the needles and all the way in but it backfires a bit. If I idle it up it is worse. If I try to back the screw out it starts to die. I think it is running too rich with the needle all the way in. Maybe I got the wrong carb. This carb has a different throttle hook up. And the fuel inlet comes straight out the side instead of a 90 degree elbow down to the fuel pump.
Any advice is Welcome.
