Idle trouble - 82 honda ATC 185S

[JGedmin]

I've been working on my ATC185 and seem to have everything running fine with the exception of the Idle. When it is in neutral, the RPMs shoot up really high and I found out the hard way that you shouldn't put it back in gear when it's like that. I picked up a rebuild kit for the carb thinking that would help out, but it's running the same as before. I think the problem may be with the throttle linkage. the little cylinder that slides up and down doesn't go all the way down. also the whole thing fell apart when I took it apart so i'm not sure if I got it back together right. the little "V" shaped deal that goes on the spring I assume acts as a retainer for that needle, but the way I have it set up the needle can move up and down on its own. does anyone have a diagram of how this goes together?

There were some leftovers from the rebuild kit so i'm not sure if I missed something. There is a very small o-ring and washer, and also the float needle valve didn't fit the same as the original one. I reused the original since it was still sealing properly.

There were 2 jets in the kit... one stamped "95" and the other "100". I used the "95"... which one should be in there?

what does the original jet have stamped on it? Plus is your carb a mikuni or kaolin, I have seen people swapp them around, they are very similar but different, either way the needle in the accelerator pump should not be sliding up and down. there is a jesus clip that goes on the main needle, that should be clipped in the middle slot, put the needle through the hole from the top down, then install the retainer clip so that it holds the needle in place now put the spring over that and compress it, finally attach your throttle cable, if the needle still moves up and down, you have some serious problems with your main jet and are going to have to open the puppy back up, to find the blockage, or you might have a bent needle. good luck

Stock jet is the 100.

Hey welcome to the boards. You may want to try just getting a new eBay carb for it. I did for my 200x and it worked wonders.

Do you happen to have a pic of the 185s? About how long have you owned it? I sold an 82 185s in fall 2008 and I'm in the Rockford area.

i picked it up in the spring from my buddy's uncle who was the original owner.

thanks for all the info guys. i DL'd the manual... helped a lot to see pics.

i dont think anything is bent... just assembled wrong. it is a kei-hin? carburetor. the jesus clip was on the 2nd from top notch so thats where i put it on the new one. i'll put it in the middle when i get it back apart.

2nd groove from the top is what the manual says.

MonroeMike is right about the jesus clip placement, I have been working on a mikuni carb too much lately for my dx 225, before you screw the throttle pump assembly cak in make sure the needle doesn't slide or something is wrong. The small o-ring and washer go into the pilot jet area, in this order o-ring washer jet, turn it all the way in till it stops being careful not to over tighten it then back it out 1 and a half tuns for general idleing may have to go in a lil or out a lil per trike and carb

I've had at least 2 'new' tirkes do the same thing lately.

the w shaped spring clip flips out and will not hold the main needle down so it gets sucked up or falls down and had me scratching my head for 2 days. the W clip holds the needle down in the bottom of the cylinder and is different from the c or e shaped clip that hold the needle in whatever vertical (elevation) position for off idle mixture.

the return spring should hold that 'w' clip down because it really has no other reason to stay where it should be...oh and they DO fly across the gravel driveway.

if it simply goes to ful throttle and stays there , the slide is missing the idle adj screw inclined plane ramp..

I can only say that because I've done it more than once.

those are the easy checks.

then it would be onto oddities like intake air leak, ripped boot, rolled broken 'o' ring at the head etc etc

I've had trouble with those rebuild kit's for my 185s in the past. It was a good kit and I got it from dennis kirk, it just didn't work, It even crushed that brass emulsion tube somehow -and that cost as much to replace as the kit- dennis kirk came through and refunded the kit so it wasn't a total loss.
I did rebuild two of those carbs this year, my own and one for buddies 200x, which replaced a ebayer cheepo carb that never worked right. I used oem honda parts for both. One cost $45 in parts to do, the other was $65. My 185 started first pull with no problems, and the 200x started third kick, both ran great afterwards.
Get a print out of the honda parts breakdown picture and follow it to find out where all those spare parts go. My manual showed a similar carb to what I had but some of the little parts were missing or in the wrong spot. I would have never got it right without that picture.
On my 185s I found the needle loose like yours, if I rember right it is soppose to be secured to the slide with that clip with a spacer, and if the needle is loose it can catch on the seat and not fall into place corect then it may let fuel through the main jet at idle. It never happened to me, but maybe its what you had. On the 200x card the spring clip i got did seem tight but plyers solved that issue easily.
Other things to check: is the slide in backwards, and do you have any air leaks? I had the oring on the flange like to fall out of place on one carb once. also the intake flange between the carb and the cylinder on my 185 cracked through and there's another oring to check on the head side of it. I always thought it was rubber or plastic, but it turns out there aluminum so if you do see a crack it's likely to be all the way through.
let us know how you do.

If you buy a "new" carb from ebay the best thing to do is take it all apart and make sure everthing is the way it should be. I got one and there was a little pice of steel in the float what would make it hold open so it would over fill and run out the over flow. Honda stock carbs are hit and miss I have had some that work and some that make you want to pull your hair out the brass seat for the needle are worn out and will make it run rich.

after some more tinkering last night I got the 185S running like a top. idles perfect. plenty of power. no smoking.

i pulled the carb back apart. i put in the "100" main jet. had to fish out the old o-ring out of the pilot bore and put in the new one. then tightened down and backed it off 1 3/4 turns. I then installed the jesus clip and "W" clip properly. started it up and same idle problem was there so I started digging a little deeper. with the carb off, the cylinder thing slid all the way down. when installed on the throttle cable it didn't so i started looking for adjustment there. The throttle cable was backed out of the screw on cap on top of the carb. i didnt know it adjusted there, but i screwed it all the way in and then it seated all the way down... then i was able to back it up a bit with the adjustment screw. new air filter and exhaust gasket installed as well. looks like i'm going trail riding next weekend. thanks for all the info and suggestions.
