UPDATE.... I never thought I would be able to do this as I do not have the skills for it ( I was wrong)... Could not get my kart to do more than 24/26 mph.... With everyone's help on here (and you guys do know what you are doing) I watched You tube videos and accomplished this... 1. Adjusted the valves... 2. Changed the carb out to a 26mm one... 3.Actually opened up the case and changed the weights on it to 12g and a 1500 rpm spring...4. Flow-thru exhaust... Now here comes the amazing thing to all of this... IT ALL WORKS was able to put it back together (and had no extra screws left over)... Now it gets up to speed faster before it used to crawl, and I clocked it @ 35 mph... All of you gave me the courage I needed to make it happen and I am very happy...
Thanks... Bob...
