[replyingto=ej132]ej132[/replyingto]9g sliders, equal to 8g rollers, was just a bit too heavy for me and my former setup. However, with a lighter performance variator 8g would be a great place to start. For the stock variator 5-7 should be good depending on other factors.
I'm sure you know this, but the a/f screw doesn't effect the main jet very much. It only effects up to 1/8 throttle or so. The A/F screw works with your idle jet for low speeds and idling. If your screw is all the way out then your idle jet may be too big?
Here's some info that Alleyoop gave me regarding popping sounds and rich/lean conditions.
Hope this helps some.
Good luck!

Every motor is different and what works for one may not work for another. One will tell you this another will tell you that.But if you listen to the sounds it makes it will tell you what the motor needs.
Here are a few tricks of the trade this will help you get it right:
1. Popping while accelerating is a RICH condition.
2. Popping while de-celerating is a LEAN condition.
3. Burp Sounds accelerating is a LEAN condition
4. Backfires are a Lean condition.
Possible causes for above and fixes:
1. Here the problem is it is running OVERLEY rich and the main jet is to big.
2. Here couple things:
a. You can richen up the Fuel Ratio Mixture
b. Idling to low Bring up the idle a little
3. You can richen up the Fuel Ratio Mixture
4. Usually caused by it Leaking where the Pipe Connects to the motor. Bad air leaks cause the backfiring many think it is because it is to RICH but it is the OPPOSITE sucking in air causing very Lean condition and this can damage your exhaust valve.

Maybe that's just because I have a 1p39qmb though.
