carb tune

[old max]

What is wrong- when trying to adjust a/f screws i turn them in all the way [gently] and the engine does not stumble, i mean the engine idles @ 1000 rpm like i' m not even messing w/ the a/f screw. It does this on 2 cylinders, one on each side . the other 2 cyls react normally. old max P.S. i'm no mechanic and i can prove it.

Hi,
I'd say that something is clogged/blocked???? Try the peashooter??

Lew, i did the peashooter already- carbs look pretty clean- it runs good at high rpm but just does not sound smooth at idle. pulled plugs and they look good.

have you changed out any jets? perhaps the pilot is too big?

mine didn't sound any different either, i'll be honest. i had to bring it to a shop with an a/f meter to see it change, which sure as shit it did.

I had the exact same problem & did this procedure to clear the idle circuit & all is good, see the 1st post on this subject. http://www.vmaxforum.net/showthread.php?t=18908
