If any of you guys reading this knows about carb tuning any help would be appreciated.
Current setup:
Keihin PZ30 pumpy carb
Jetcone style free flow air filter
Needle was set on the top slot so needle was all the way in
Main jet has no markings on it so cannot tell but according to the internet it might be a 108
Symptoms: The quad starts fine and idles fine but does not throttle. With the choke halfway engaged I can sort of get it to rev to about half throttle but anything past that it just sputters. I have tried adjusting the air screw from all the way in to dropping from threads, about three turns out seems to be the right place but overall it has oddly little affect no matter what setting it is in.
I have now set the needle all the way up to see if that did a thing, going to reassemble everything and possibly report back in a while. Any ideas welcome.
