wont stay running

[charlie21]

my 97 rm 125 was running awesome until i was stupid and messed with the idle screw and now every time it fires up it dies like it isnt getting enough fuel how do i adjust it so it will start and run.

Start and run, or start and idle?

 

[charlie21]

start and run then i can fine tune it.

It starts but only when i prime it with a few twist of the throttle and then it dies like its not getting fuel and i pulled the plug to look at it and it doesnt even look like it has any fuel on it at all.

Turn the idle screw in a turn and try again.

 

[charlie21]

all the way or what

note: On any two stroke I have ever seen twisting the throttle does NOT "prime" the carburetor. Four strokes usually have accelerator pumps, two strokes do not.

A starting point that should get you close is to turn it all the way in (gently!) and then back it out 1-1/2 turns.

Then set the idle speed up as high as you need to in order to get it to keep running. Adjust the idle mixture for best idle (highest speed, smooth). The drop the idle speed as low as you can and have it keep running and repeat.

When you are all done, take it for a hard ride and then repeat the process.
