Hi All,
1984 ATC 200s is killing me! I cannot get this thing to run worth a crap.
Here's what I've done so far:
New rings and valves - it was smoking.....solved !
New brakes....solved!
Rebuilt carb - no change in problem!

Problem: Run very sluggish and misses out, very hard to start.

Haven't touched CDI or coil...may be my problem?

$800 so far and nearing insanity!!!

Please help!

 

Did you tank the carburetor before rebuilding it?
Did you adjust the valves after you got it all together? [#1 problem for hard starting]

I don't mess with these old carbs much anymore. By the time you get it done right, you spend more time than what it is worth and you still have an old carburetor with cheap parts inside and will likely require another rebuild in as little as 2 years....if not sooner. I usually go with a new carb if the trike is in pretty decent shape. You can get a brand new carb ready to go for under $150 if you shop around with a few Honda dealers.

 

Yeah, I dipped all of the carb parts overnight and blew everything out with compressed air then reset it to factory specs. It looked to be in good shape to me but I thought about buying new factory jets in case someone has changed them in the past.

I set the valves at .05 at TDC when I assembled it and rechecked them after I ran it some.

Anyone know how to test the coil and CDI unit?
I did notice that the plug had a lot of carbon on it. (bad spark?)

 

Is that .05 .....metric or inch?
I wouldnt suspect the ignition yet...it runs at idle. There can be intermitent problems, but usually they fail and thats it.
Sounds carb related to me, and possible the valves are set wrong .
Hows the compression?

 

It could be your stator .sometimes they can play up intermitantly.

 

I'm having a hard starting issue with my 200X as well. I'm going to pick up a rebuild kit and give the carb an overhaul. I've rebuilt it once, but without the kit. I have a feeling some of the old bits are just worn out.

The new carb idea sounds great....but the only thing that worries me is finding an manifold that fits. From your other post, the only one that will work is discontinued. [img]i/expressions/face-icon-small-sad.gif[/img]

 

Glenn,

Both carb types will work with ANY intake manifold.........including the one that you have now. It's just that you can't realize the full benefit of the larger carb with the smaller intake. It will still run perfectly fine.....and will not require you to make an airboot either. You just will not notice the gains that you would have gotten with the larger intake that matches it.

 

KNOWSALOT,
Ah, I see. I thought the manifold was needed to allow for proper mounting on the 200X. The frame is a bit tight around the carb.

Will the bigger carb make slight gains, even with a stock manifold? Are they hard to dial in on a 200X (jetting wise)?


As far as carbs go, I take it a late model XR200R carb will be the one to get?

 

Glenn,

Yes, the carb I am referring to is the one from the late model XR200R.

It can be used with any inake even if the inside diameter is off from the carb and while I haven't ran into a jetting problem with any of them yet on any bike, including a bone stock 185 a few months back, I am not going to promise that no jetting changes will be needed in all cases. We know all to well that nothing is taken for granted when it comes to jetting.....lol

The XR carbs also have the quick access plug to the main jet on the bottom of the float bowl which makes jetting changes a breeze. The 200X carbs also had this feature, but it was not on any of the other 185 and 200 trikes.

The carb would work on your X with no modifications to the intake, airbox ducting, or throttle cable. It is a bolt-in swap and as far as gains are concerned, it is noticable.....but not as noticable as if you have had the matching intake ofcourse.
The one thing that you will notice immediately is that the bog that you used to get when you go full throttle from a stand still is almost non-existent with the XR carb. As for horsepower numbers, I doubt that it bumps it up any unless you have other mods already done to it. The XR carb just makes better use of the power that you already had.......but couldn't apply it as efficiently as before.

If you have an exhaust, filter, and/or a cam.....the carb will then make a very noticable difference....even with the smaller intake.

 

hello, did you pull the needle jet out from the bottom of the carb? if you pull it out there is small small holes in it and if some of them are clogged it will not run right you will have a slugish take off and hard starts also,that maybe something to check out, tom
