98 te 610 carb question

Yes, this is a repost. If my bike is not running well right off the bottom, when I,m trying to go slow on trails, could the size of the idle jet be the problem? Acceleration is fine. The carb. is clean and this sputtering can't be tuned out with the idle mixture screw. It does have a Big Gun exhaust header and pipe. Any help is appreciated.

might check the air mixture screw, sometimes the rebound spring gets lost...if its missing find a replacement.

Thanks Chuck, I just went out and checked that and the spring is there. This is a bike I just recently got running. It was a basket case. I don't have more than 5 minutes time on it. After I checked the carb. for that spring, I rode it up and down my road and found that sputtering problem to be all up and down the throttle range which seems to be a different problem. Any Ideas?

wow..could just be dirt in the jets, id say, pull the carb, and remove them, clean them well with carb cleaner, if you have air, blow them out well, if not use a small needle to pick them out.
look for dried fuel ect,.
if thats not the issue,,,hate to say it....could be the flywheel magnets loose..

I cleaned that thing twice and I do have air and blew the @#%& out of it, but I will do it again just to be sure and it's free. I will get a fuel filter on it as well, it did sit for 5 years. I had George at Uptite check the flywheel mags and he said he couldn't get them off and they should be allright. This was before I got it running and thought that was the problem. I'll be back. Thanks, Joe

O.K. I took apart the carb. again and upon close inspection found that only one of the floats was making contact with the shut off lever, which explains why it would somethimes drain out the overflow. I think maybe it could also have been making the bike run rich as needle placement didn't seem to make any difference, nor did the choke most of the time. The mixture screw has also become relevent again. It's not dialed in all the way yet but I think I have at least eliminated one problem.

keep us posted, i have the same bike!
