My first question is what type of carb comes stock ona blaster? I just bought a project bike set up for drag racing. I had everything worked out on it (I thought) well except for the suspension. So today i just got my new clutch cable in the mail. There wasnt one on it when i bought it. Back to the carb, the clutch arm seriously sets on the carb wall, and will not move unless i take the carb off. The carb thats on it is a Keihin PJ Im pretty sure. And theres no tension on the arm but i guess thats just a worn out spring. I cant creat any clearance because the other side of the carb already sets against the bottom end. So only thing i can figure is that its not the stock carb. Does anyone no what going on?
