One other thing on all of these 350 Foremen I've bought. Only a couple have had carbs on them, and they look different than any other carb I've seen on a Honda.

Bowl and jets appear to be about the same as other carbs, but there's no "top" where the slide comes out. There's what appears to be a lever up there. The two that I have are both gunked up so bad I can't tell what's supposed to move and what isn't.

The "kinda running" 86 I bought had an aftermarket carb that looks like a 300 carb on it. I think I'm going to try to clean up the OEM carbs and put one of those on it.

Two on fleabane for <$50

The OEM carbs are easy to clean up and adjust. I bought the cheapest china kit I could find for mine and used just the gaskets and rubber 0-rings out of that china kit (the float needle valve was fine in my carb, the china kit needle was garbage though)... then threw the remainder of it away. The FSM outlines how to synchronize the throttle slide with the butterfly opening... if you do that when putting it together it will improve throttle response and you'll like how precisely it tunes...

EDIT:
If you buy a cheap kit for soft parts... make sure the kit has a new lipped seal for the choke plunger. The lip faces up (it seals air from entering around the plunger) when you install that seal.

I'll have to see if I can get it freed up. I looked and the 89 rig I have also has a carb on it that appears to be OEM.

On the 87 the slide is frozen in place. I've got to get the thing apart without tearing anything up before I can try to clean it up.

Sounds like you'll be boiling that 87 carb outdoors... yuk! Hope you can save them both, they are high dollar items... but usually fix them for less than $20.

The slide assembly is weird on those like you said. After taking the top cover off you take the linkage apart and pull the slide shaft out of the carb body.

I rebuilt two of them, replaced the floats in both. Be careful with those screws the heads strip easy. And with that plastic main jet holder; they are hard to find

How does the linkage come apart? I can't tell if that's a screw in there or not. If it is, someone has done some major buggering on the head....:icon_frown:

Uhh ohhh... Sounds like someone has been in there and trashed the place. That is a set screw alright... :-(

It looks pretty common to me though, so it should be easy to buy at the hardware store. There should be a shim washer or two on that shaft between the carb body and the buggered lever that limits endplay on that shaft and helps keep dirt out of there by taking up space.

I guess I could look in the FSM I saved instead of making yall do the legwork for me!

I'll soak it good and see if I can get it apart.

Hey, I don't mind at all Jeep! I'm itchin' to go out and tear mine all apart again every time the sun shines... talking about this stuff might help keep me out of a snowbank for another month or two!

There’s a nut and threaded stem for the throttle cable; loosen the nut and give the cable some slack. Then slip the end of the throttle cable out of the carb linkage (circle in photo).Then you have to unscrew the threaded cable stem from the carb body

Otherwise that linkage does not come apart except the top piece has a shaft that secures and allows the throttle valve to move

 

[Jeepwm69]

Yeah I have it off the bike and got the butterfly free just squirting some PB Blaster on it and moving it around a bit. Where the throttle assembly hits the little lifter plate is where it stops. Looks like the slide and that top assembly are frozen up pretty good.

Yeah sitting inside thinking is 99.5% of the "work" I've done here lately. I'm lucky if I get to go out and look at stuff to see what I even have and what I need.
