- Start date
im confused by what your saying, your saying when you let off the gas it idles iregular or does it die? what are all your mods and what is your main jet?
When was the last time you tested the motor for air leaks.
Never fiddle with the air screw , only to adjust the idle.
Idle adjusting.
Start with air screw 1.5 turns out.
Set idle screw so that it has some sort of idle. With TORS it is the big screw under seat on top of unit. With no TORS is is the brass screw midway down carb body.
Warm up motor and then set idle screw for a faster idle, 2000rpm+
Adjust air screw either way to get the fastest idle.
Adjust air screw a little at a time leaving 10 secs or until the motor to responds.
Re adjust idle screw for desired idle .

A #290 - #300 main should be good with your mods, unless you premix and have very cold weather.
Methinks it could be sucking air!

Most likely at reeds, but further testing will be best. Don't overtighten reed screws in attempt to fix that leak. Sealer, and or maybe new gaskets will be needed.
yea awk, my best bet my last dollar it's leaking at the cage and the jetting is a tad off. but yea dont overtighten at the cage it'll cause warpage of the gasket.
