your thread heading, and our responses to it, all are stock 26mm carb related.
now you flip the script and say 28mm
Lol sorry my question was for general info on needle selection, wasn't aware that it wasn't required on the stock carb.
Seems the pilot jet is simple to set your airscrew will "tell" you to go up, down, or leave it alone.
Main jet and even needle position changes are plain as the nose on your face once you cut the threads off a properly run (wot or 1/2t) plufg.
But there are so many possibilities,and thing that can throw off needle selection, a pilot jet that's a size off, or a main jet that a couple sizes rich or lean can really throw things off, (so I hear anyhow).
My plan is to simply, pick a needle set it at mid clip, get the pilot, airscrew and main (pc verified) on. And then experiment from there concentrating first on getting a good chop at 1/2 throttle then on he sounds and feel of 1/4 to 3/8 throttle and right around 5/8 as well, holding each position for as long as possible from rolling rpm to where it stops pulling, in 4th of 5th for low throttle and 5th or 6th for higher 5/8 throttle.
Might also fan the clutch at moderate rpm as see if or how well it comes on the pipe.
My thoughts are that if the needle chops nicely at half throttle, then the clip will need to stay and the needle itself will be responsible for whatever happens on either side of half, and should give me a good idea of more or less taper, starting sooner or later???
I haven't a clue whether the above plan will actually work in practice but based on my limited knowledge, and barely workable sense of rich or lean, it sound like about the best I can do toward figuring it out.
My guess is I will carry a couple spare plugs and needles with me when I go out to the trails, because it about the only place I have now that I can run it enough for anything funny to show up.
I used to have a little powe line right of way at the end of my neighbor hood that worked pretty well for testing, but some punks spun it up with their little 2wd s10's and now it's gsted.
Anyhow let me know what you think of my general plan, as I am sure there is plenty of room for improvement, and hope their is an easier way to do it.
Thanks deebee
