Surging when coming to a stop

[zfrederick]

When I come to a stop the idle goes high for a few seconds and then comes back down. Is this normal. I couldn't find anything in the threads related to it.

Outlaw 500 - 2006

Hello it may be sucking air somewhere

[joshr08]

it sounds like air but i dont think with the fuji motor it would only do it for a sec or two then drop back down. Could be the slide hanging just a bit before closing. Im sure a good carb cleaning would take care of the problem.

I did a rebuild on it about 5 months ago. I will take it to the park today and blow it open then clean it tonight and see what happens. Everything looks sinched up but we will see

Took it out to slades park today and ran it about 20 mins before it died all together. I could get it running at mid to high throttle while I was being pulled but black smoke out the back. Got it home and noticed the main needle came out of the diaphramg plunger thing. On the bottom side in the black plastic slider. Put it back in and it revs up and down fine now with a crisper throttle. With that said I see that the needle is only held in by a rubber gasket using pressire. Is there an upgrade out there to give a locking mech like alot of other carbs that I have to hold it in. All others I have use a twist locking piece to hold the needle into the plastic slider.
