    Thanks Jenn! Maybe I'll just get a new slow jet and take it from there. I rebuilt and cleaned this carb about 8 months ago, but maybe I'll pull it and take a look at it again. At the very least, I think I'll toss in a bigger slow jet. The dealer should have those I think....

    I pulled the slow jet out of a spare carb I have. It's labled "40". I'm going to hit the dealer today and see if I can get a 42 or 45.

    Be sure to post and let me know how this works out for you. I'm still tweaking my carb as well.

    Will do. I'll probably get into the carb tomorrow morning. I'm doing some riding Sunday.

    It's one thing after another! LOL!

    I can start it, but I can't get it to idle correctly. I put in a 42 slow jet, stock is 40. The trike starts pretty easily now, even when hot. However, I can't set the idle correctly. It's either too high, or way to low and stalls out. The different between the two is like 1/16th of a turn on the idle screw. I'm kinda stumped.

    Pull the carb slide & have a look where the idle screw contacts it, there might be a gouge on it or a wear spot. This makes the idle hard to set. Using a small file & some patience you can smooth it out.
    Also, check the idle screw for straightness or a buggered up tip on it.
    You're sure there are no air leaks antwhere? They can also cause idling problems.
    A whole bunch of trikes.

    I'll take a look at the slide, I hadn't thought of that. I'll double check again for leaks just in case. Damn carbs! I see why fuel injection is getting popular.

    My 200x that I've been complaining about has a big gouge on the slide too. I've been thinking about taking a Dremel to it to see if I can smooth that out and make it possible to adjust the idle...

    I would Fix the grooves in the slide. On my trike I have just given up on getting the idle right for all conditions... Can you reach the idle adjustment screw from your riding position?What I do is. when cold use choke and kick it up.. use the throttle to get it going and adjust the idle screw for smoothe idle...as it warms up I let the screw out for smoothe idle...as I ride sometimes when I stop it needs a little fiddle to stay smoothe. I have a custom carb and everything else and this works like a charm. Once you get used to these small adjustments it will run ok.

    Oh also the slow jet has to be in the right range! I have not read all the posts here but I know on my stock carb I needed the next size slow.

    I messed with this a bit today. I backed out the pilot screw to fatten up th e mix a bit. However, I'm still getting some "hanging" when I rev the engine; the idles doesn't drop right down to idle, it takes a few seconds. I'm kinda lost... I'm running a 42 slow jet vs the 40 stock.

    My 84 200x had that EXACT same problem. I checked for air leaks for days, rebuilt the carb (all new jets, o-rings, needle, EVERYTHING), adjusted the valves, adjusted the pilot air screw, adjust the idle screw, I did everything. Anyway I got it running to the point where it would idle high and a few seconds later the idle would back down and be rock solid. Last thing I thought to check was the ignition timing and bingo!!! I pulled the c.d.i. cover off on the left side of the cylinder head and the pulse rotor base plates notch wasn't lined up with the notch on the engine (know what I'm talking about, if not let me know). It was only off about 1.5mm, a very very small amount, I guess it had slipped because the screws securing the base plate had loosened a little. Anyway after lining the notches back up everything was fixed...talk about relief after about a week of frustration, anger, and more anger at the damn thing. Now the idle is fixed perfectly.

    I'm willing to give pretty much anything a shot at this point! I think I'll check that out this weekend. Thanks for the advice!

    Ok kids! I rebuilt and older carb I purchased awhile back so I may give that a shot. I did notice some "dents" in the grove where the idle screw rests. I should check my current carb.

    I think I'll try the CDI trick solid snake mentioned as well.
