I have an 03 sp 700 and it runs a little rough from about 1/8 to 1/2 throttle, other wise runs great. My question is does this carb have an air mixture adjustment screw? I have looked all over and cannot see anything on it. I have found a hole next to the idle screw on the bottom, but the hole is not threaded and it goes into the area where the throttle cable connects and I cannot figure out how a mixture screw would work there anyway. Any help in figure this out would be appreciated.
thanks
Martin

 

it is covered by a brass plug, you have to drill a hole in that brass plug and take a self tapping bolt and pull it out
