I Have a 2000 Blaster. Just got the bottom end rebuilt with ProX rod. Topend with ProX piston & gaskets. Now, i bought this quad without a carb. I got a carb from another parts blaster. The current carb i have has no idle air screw. So i ordered one and im ready to start breaking in my engine with its first start up. How should i set my idle??? I dont want to start it up on the engines first ever start and have it at an extremely high idle and burn the rings out quick. What should i do?
