So I was having some issues with the carb pictured so I bought a new one and I got everything hooked up and once I got it started it just went wide open throttle (had to turn the killswitch on and hit the throttle to kill it) so I put the Keihin back on and once I got it kicked over after a few tries it was idling just fine then it just started revving up to wide open throttle it’s going to the shop this week but I’d like to get it fixed so I can save that money the very last resort is selling it which I don’t want to do

Is this an original rebuild kit? I don’t want any aftermarket stuff
