So I’ve been working on my xp for awhile now, finally I’ve gotten it all put back together and running. But when I start it the engine immediately runs at 6 to 7000 rpm with NO throttle. I’ve confirmed this by checking the throttle flaps in the carb and the cable connection to the carb assy. My mind immediately went to check valves on fuel tank pressure release. But there’s no clogs. I did replace the oem pressure release valve with a normal check valve that I bought on Amazon. They are fully functional though and I went through them tonight and started the engine again and… same problem. Only thing I can think is maybe the tank is providing enough pressure to boost the fuel and cramming fuel in, but not enough to push air out of the check valves? It makes no sense to me. Any help is appreciated. Thanks!
