I cleaned the carb, clogged up big time.. I put everyting back on and it starts right up and idles and revs great.. when I went to take a quick ride it would only rev up to about 4500 rpms and stumble. I can pull the choke and it will run great, all the way to red-line.. should I try to clean it again?? oh, what should the pilot jet be turned out 1-1/2 or more? thanks for any help..

 

Several others have had this problem recently. It turned out that the diaphram/boot was out of place. Recheck that. If that's not it, I dunno.
