do a leak down test.. should hold 5-7 psi for 10 minutes no prob.....if it leaks out you need to find where its drawing air in and fix it....if its not drawing air in pull the carb out (leave it connected to the cable and have someone work the throttle to make sure the slide closes completly everytime. and 1 more thing...for your mods did you ever move up an idle jet? i had to go up 1 size on mine when i piped my blaster. |
