mgs4 Posted June 3, 2015 Share Posted June 3, 2015 is there default settings on mixture and idle screw, i can get the bike started takes a while but i have to keep the revs up. from what i heard mixture screw is all the way in and 2.5 turns out and no clue on idle, can anybody step me through on how to set it up just to get it running i have tuned carbs before but not on a 2 stroke and they have allways ran just fine tweaks any help would be a great help Link to comment Share on other sites More sharing options...
YPVS TONE Posted June 3, 2015 Share Posted June 3, 2015 Screw the air screw all the way in until it is lightly seated then back out 1.5 turns out and this will give you the default setting. There is no setting for the idle/throttle stop screw as you just screw in or out until you get the correct idle speed. If you still can't get it to tickover by doing the above it may be the pilot jet is blocked and requires the carb stripping and pilot jet blowing out.

mgs4 Posted June 5, 2015 Author Share Posted June 5, 2015 hi, i did as you said, it wont start unless throttle is wide open and a squirt of easy start, wont run without hand on throttle, idle screw does not seem to make a difference, stripped it down it has a 240 jet in it and the pilot is clear i can see light through it. its also very smokey im wondering if it the throttle cable incorrectly set up any opinions please anyone Link to comment Share on other sites More sharing options...
blackhat250 Posted June 5, 2015 Share Posted June 5, 2015 The choke aint working then, and if it don't idle, then the idle screw must be the wrong one, [ if it does nowt] take it out, check it, take off carb -and looking thru from rear, screw idle screw in, it should lift the slide, , get that pilot out , it cant be clear, The choke well [ in float bowl, ] needs cleared, blast it thru, should see fluid come thru small hole Link to comment Share on other sites More sharing options...
