Hello i'm currently tuning the carb after a engine rebuild. At 4:10 you are using the main adjuster on the throttle cable won't it mess with the tps sensor on the cable ? On mine the tps is the black box on the throttle cable where it splits to carb and oil pump cables. Do you have the same?
Also I'm still on the break in first tank with 50:1 premix plus oil injection. Does it make sense to tune the carb before the next tank?
Thanks for helping

How much of a power increase did it feel like with these carbs?

Where is the high speed screw. Mine bogs at 3500 -4000 rpms I tried adjustments low speed to little success. Any suggestions?

Does opening the H and L screws lean out the mixture?

Did you rejet it because of the exhaust change?
