Carb

Need help tuning my carburetor
As Larry mentioned, you didn’t mention any modifications, but assuming you mean adjusting your pilot air screw, this post should help from stock to modded, try this: https://www.blasterforum.com/threads/adjusting-your-airscrew-pilot-jet.51060/

Before you go ahead and adjust that, make sure you adjust your float height correctly, here’s another post by that same user teaching you how to do that! https://www.blasterforum.com/threads/float-heights-and-how-to-adjust-them.50565/ now this post only goes into detail with Keihin and stock carbs for blasters, so if yours isn’t on this post, check your owners/repair manual on the correct float height, if you do not own one, there should be a copy on this forum you can find! Hopefully this helps! I’m no professional but this is what helped me!
