I pretty sure all the idle screw does is limit how much the carb is allowed to close. Personally, I'd wait, I wouldn't want dirt and grit getting in the hole where the screw goes. Hope you ordered the spring with the screw also.
Yep I did, for some reason its taking a long time to get here. Normally when I get things from Horizon it takes about 2 days, It's now been a week....
