Now ive got 2 more questions for you fine gents. 1 what cause the full fuel screw from goin not much farther than the stock pos. Ive had trouble with them before but this is worse than any ive every worked on. Its hard goin in and out. had to get the vice grips to get it out and it wont go anyfurther than it was. 2 It doesnt feel like im getting the full pull on the throttle. Im tryin to help a buddy out he got taking for 300 at a shop for a "tune job" all they did was run the vavles and pull the afc spring out.
