1995 Yamaha Timberwolf 250 idle

[dcata]

Got a question and hopefully find some help. I have a 95 Timberwolf 250 that I picked up and it didnt want to idle. I have rebuild the carb with new kit replacing all the jets and float seat. Blew out the ports with the air compressor after I soaked the carb and cleaned the ports with a fine piece of wire and it still wont idle on its own. Has new air filter. I had it running and sprayed around the carb and carb joint and didnt get a rapid acceleration as if I had a leak. I read somewhere how the standard jets are like a number #40 and people have replaced them with a bigger jet. I called the local dealer here and they said they cant order jets and was wondering if this could be the problem and if so where can you order them at. Any info/help is highly appreciated. Sorry for being so long, just want to get as much info out as I can.

how about throttle cable adjustment ? idle adjustment? does it run good otherwise ?

I havent done the throttle cable adjustment yet as I didnt really understand it, but I will look in the manual again tonight when I get home. I have the pilot jet at 2 1/2 turns, but I just noticed that the needle jet isnt clipped in like it is suppose to be. Im going to fix that when I get home from work tonight. Thank you for your response as it made me look a little harder and now might have the solution.

the pilot screw is the high mixture screw. this is for full speed. does not effect idle. on handle bar were the cable connects to throttle there should be an adjustment.

Ok got it on the pilot screw. I will look tonight when I get home at the throttle at the handle bar adjustment when I get home. Again thanks

Just a update. I put the lock tab on the needle jet in the center of the jet as I had it running lean and adjusted my throttle cable and now the Wolf will sit and idle and has no hesitation when I throttle it up. I want to thank all that replied for their help and info as it paid off. Awesome forum..........

Okay im going riding tomorrow and went to start the Wolf to make sure all is fine and it still idles on its own and acceleration is good. But when I rev it up and at idle im still getting the black smoke of either running rich or lean. I know on the needle jet that depending where you set the lock tab it can cause you to run either way so I put the lock ring in the center on the needle jet. Any other suggestions on something I might be missing. Thanks

I thought the pilot screw (pilot circuit) was the exact thing that controlled idle?? I am confused now
