Go to youtube and enter "clone carb jet change" and select the go power sports video. You will leave in your present emulsion tube but replace the main jet with the new one. Again use the the new part to replace the old part holding the bowl on. Screw in the adjustable needle to maybe 1 full off being fully seated and work from there. Just want add to this no doubt about building your own engine and having it run even better than expected is a great thrill BUT also tuning it in so it has razor sharp throttle response is another great thrill. ENJOY
