Does anyone have fuel mixture screw setting and valve specs for this quad?  

digging through the books here, hopefully i'll have you an answer before too long.  

darn book not showing it.
will try to call in a favor tomorrow and find out.

i do know that carb air/fuel adjustment screw is on the bottom of the carb, or so the book says.....

as far as the break-in valve readjustment, it is noted that it isn't necessary unless the machine is having valve related problems.  

iam looking for information on valve adjustments on my 1999 kingquad 300. can you help me?
