maybe its air then? i went riding on new land and didnt want to sit and mess with the quad so i just rode it how it was...

ill mess with it soon tho.... the screw is directly on the bottom side of the carb...takes like a number 3 flat blade screwdriver to adjust it...

(o and pushinthelimit, i think your right, i think im lean on the idle circuit, because its 20 degrees with mostly high speed riding and the fan actually kicked in today for the first time this winter, and i could actually FEEL the engine heat through 3 layers and my carharts!)

so if that screw is air mixture...i want to screw it IN? therefore RICHENING it?

 

4 strokes have a fuel screw, regulates fuel flow untill 1/4 trottle. 2 strokes have an air screw, regualtes air flow etc...

 

Ummm no.

 

Do you wanna argue with me? Trust me I'm right on this one. try to find a 4 stroke carb with an air screw, lol.[img]i/expressions/face-icon-small-wink.gif[/img]

 

If the screw is on the engine side of the carburator it is a fuel screw. If the screw is on the air filter side of the carb it is an air screw.

 

On a 4 stroke motor huh? I never heard of an air screw on a 4 stroke motor, and if it was important to jetting I would have heard of it...

 

Oh ok i see now... But I still never heard of an air screw on a 4 stroke carb.... Only 2 stroke carbs.

 

I never said thumpers have air screws. I was just pointing out where they are located. Even though the link below doesn't say what I said.

Fuel Screws

 

Good link.[img]i/expressions/face-icon-small-smile.gif[/img]

 

The TM 45 has an air screw, no fuel screw. Just like a 2 smoke, turn in to richen, out to lean.
