    cb360 carbs

    the bike i bought two weeks ago wasn't idling well so i pulled off the carbs planning on cleaning them, maybe putting in new gaskets or whatever. i didn't expect this:

    so now i need new carbs i guess.

    unless someone has that flap/panel thingy chilling on the shelf on some busted up carburetor that they'd want to sell me?

    assuming not... are cb350 carbs interchangeable with the 360s?

    also what do you guys think about this:

    not that i'd be really excited about putting in carbs that cost almost as much as the bike itself but if it was gonna improve performance and make things less of a hassle you could probably talk me into it.

    You should have already heard about SFL and their 'correct' jetting. (190~200 main jet )
    Pay a little extra and get carbs that will work from a CB350 specialist, the difference in engine capacity (326cc vs 356cc)wont make enough difference to notice.
    Decent ones rarely come up on eBay but a cheap set to rob parts out of should be pretty easy to find (or use and keep the ones you have for parts)
    you may have to 'bite the bullet' if you want them 'quick'
    350 carbs don't interchange with 360.

    A better question is where the missing parts are. Did the engine swallow one or both of the missing screws? I have seen them embedded in the piston crown or the head. That could be the cause of your poor running engine, too.

    the bike does fine once you're going ten miles an hour, it's just below that that there's a problem, so i'm hoping the engine is ok. <profuse knocking on wood>
    different question:
    the big gasket you get in a carb rebuild kit:


    are you supposed to jam that into the float chamber? it looks too big...

    i really dont know if i believe you when you say it runs fine past 10mph... thats a pretty gnarly carb prpblem. really strange too for both screws to be gone. i'd get some
    mikunis if you got some change to spend.

    Yep, the big 'O' ring is float bowl gasket.
    Get some Permatex Indian Head gasket shellac compound, its how Honda originally 'glued' them in (kinda sucks you have to buy 4oz for 5 spots per carb)
    Pilot jets/passages are probably still blocked
    It's too unusual for both screws to fall out, someone probably removed them to clean carbs (or thought it was a 'performance' mod?)

    I feel like an idiot for selling my stock carbs. For 35 years old, they were MINT. The guy that bought them slapped em on his bike and said it has never ran better. Now im stuck kicking myself in the ass trying to figure out those retarded mikuni carbs from the so called properly jetted kit SFL sells.

    so correct me if i'm wrong because i really don't know much but...

    the flap that's missing is what flips when you use the choke, in the normal position it's wide open so the the flap is extraneous. if i'm not using the choke then it shouldn't be a problem... right? or do i have it backwards?

    Don't use the choke. You'll be fine.

    Just move somewhere warm.
    Canada, we\'re bigger and on top. If this were jail you\'d be our bitch.
