CB350f Carb Separation
« on: August 19, 2005, 01:15:22 PM »
Greetings,

New member here, I just picked up a '73 CB350f, woohoo!

Here's the background: I had a 350 twin about 10 years ago, but ended up selling it for $100 (stupid me) to get into sportbikes and whatnot. Did that whole thing, and sold all my stuff about 3 years ago. Well, the bug has bitten me again, and I got a great deal on this nice 350f for myself and my wife to get her license on. I'm rebuilding the carbs on it, and have hit a stopping point. Hopefully you guys can help me until my manual arrives... I've been pouring over this site for the last week or so reading all that I can, but couldn't find anything addressing this:

I've gotten the bowls/floats/etc. off, and want to separate the carbs. I disconnected the choke, but can't figure out how to separate the four carbs where they connect to the throttle arm. I'd rather not start messing with the synch screws just yet, as it had run well when the guy I bought it from put it away a couple years ago (I know the guy, and he's trustworthy, so I do trust it was in good running condition). So, how the heck do I get them apart at the throttle arm?? I see the big screws that hold the bodies together, but that's as far as I've gotten.  I will end up re-synching the carbs, as I'm going to do a bunch of other stuff first (cam chain, ignition, etc...), but want to get cleanin' these things and keep a reference point for the synch at least!

I'd appreciate any help you guys could give me to get a jump start on this before I have some documentation. I checked out the honda4fun.com site, but that manual seems like an advanced manual for somebody who knows how to do it, and basically just says "separate the carbs...".

Also, the posts in which the main jets sit (the jet held in by the leaf spring which pushes on the float bowl... I think it's the main... ) look somewhat deteriorated. They have chips around the edges, however very minor. Will this be an issue? The jet still seats in there fine, and is held solidly in place... but I want to know if I should be worried. I have an extra set of carbs, but they are pretty beat up and I'd rather stick with these...

Finally, I realize how valuable this forum can be, after I bought the carb and parts cleaner in the can with the dip bucket. Just after I dunked my first parts, I came back to check out the forums and read about how crappy that stuff is and it sure does smell bad! I should have gotten the Yamaha stuff... doh! There's $13 down the tubes, and a stinky garage to boot, that this forum could have saved me from :)

Thanks in advance, glad to be onboard here.

Regards,
-Pat-

Unfortunately, I have to swap out one of the carb bodies, as the float pin post got broken on one. I have a set of extra carbs, so these have to come apart.... anyone??

Thanks,

Not sure about the 350 but on the 500 yiou HAVE to remove all the linkage parts and pivots so you have to re-adjust on assembly. Not what you wanted to hear sorry

Thanks Brian, looks like that is what I'll have to do. Not too big a deal, as I plan to totally check and tune everything anyways.
