Have ajustments all screwed up

First make sure the rear breaks are ajusted or replaced when worn out drum to be skeemed aswell. Usally whe rear brakes are ajusted hand break will stop car on two to four clicks on hand brake rachet. If brakes is ajusted check cables for wear . Then ajust cable insite car remove hand brake cover and you will see a ajustable screw or nut. Rememeber to put the handbrake on four clicks and dont tighten screw or nut to much the brakes will lock

Refer its user manual for details.

Has anyone try to adjust the screw on the throttle,,that looks like a idle adjustment..If so that is preset at the factory,,and should never be adjusted...If the throttle plate angle is out of ajustment,,you may have to take to the dealer to get it back to factory specs...When ever that is moved,,it changes the voltage ,,

Here is a carb tuning tutorial by one of the premier diaphragm carburetor manufacturers in the business:

I know accessing the L and H mixture screws can be impossible. They sell the splined head screw carburetor tool on Ebay. I have removed and cut slots in the heads myself. I have used aluminum tubing to grasp those screw heads and also #22 automotive-type wired connectors with the plastic ends tapped over the heads of the screws. I do NOT suggest you remove them, as getting them back to their initial factory setting is near impossible.

to ajust your fuel inlet their is a screw on the side of the carb when you screw it in your leaning it out and out will richen it but you need to find the right ajustment because if to lean it out to much you will burn the piston but to rich will foul the plug

I think it is a small spanner you need to ajust it with

No you are confusing the idle screw (a thumb-screw) with the air/mixture screws, these are turned inwards (clockwise) until they lightly seat & then back out the specified amount
You should have the bike tuned by a professional who should include synchronising the carbs, this will let the engine run more smoothly, idle at lower revs ,increase speed & all-round performance speed

Please mark this as very helpful (if it has been!!)

there is not precised position you screw in for more idle and screw back for less.....

Screw each one in all they way, and then back them out two and a half times, then start it up and then ajust each until it runs smooth.

The 3 adjustment screws are Idle, high and low.
First figure out which screws are which adjustment. Tighten the screws then turn them 1 full turn.
Then start the saw and get it warmed up. Work on the high adjustment. This does take a little while. after you get the saw running at high speed work on the low speed.
