Scooter Air/Fuel Mixture Screw Adjustment




What do you think about this video?

tanner122772: Couldn't they have just put it (the screw) somewhere on the outside of the carb, instead of us having to unhook all those hoses and all that drilling?

John Crane: Aughhhhhh... always turn the screw in first counting how far until stop, now turn the screw out until the same height and in case of CC upgrade, add a quarter turn. That will get you in the ballpark. Using a vacuum gage you turn the screw until it gets it's greatest vacuum at idle, them back out the screw slowly until the vacuum just starts to drop.

Paul Shpakov: Excellent video! It's simple, and correct. Thank you!
