Got another here that doesn't turn up well. In fact I am getting the same EXACT numbers as you. I am going to put another gallon through her and if it doesn't pick up to a reasonable number I am going to check the cam timing. Saito has been known to miss on occasion and get it out by a tooth and when corrected they pick up as much as 1000 rpm's or maybe a little more. Mine runs flawless, just doesn't make the grunt it should on the top end. I've tried different fuel, different plugs, checked to be sure I was getting full opening on the throttle barrel, etc. She's just not making the power to spin an 18X6 over 7600.
