Hey guys,
I'm having some really strange behavior with my 32cc DuneRunner. Basically, it's gotten more & more difficult to start it and after it does start, after about a minute or two the idle revs start going up. It starts up very nicely at 3500-4000rpm and then it goes as high as 8000rpm. The tank is vented, I checked. Sometimes just giving a squirt on the throttle and then letting it go and the revs refuse to come back down. Carb butterfly is moving ok. The really weird thing is this: I thought "what the hell, maybe the LSN got screwed up and it's running very lean?" and I tried playing with it a bit. When the car was idling at ~7000rpm, I turned the LSN clockwise (so, giving it even less fuel) and it choked on itself, the way it does when you give it a lot of fuel on the LSN. I'm confused, anybody got any ideas?
Not sure if it matter but this is my setup:
Stock 32cc
Walbro WT1107
JetPro exhaust
JetPro silencer
