Carb...
 

Hey gang ... Been a while since ive been on , hope everyone is good . Im looking for a carb for my 76 cb 750k . Just one , I broke a stem in one of mine and it is not repairable . If anyone has one , or an old set , PM me .

Thanks a bunch !

Twin cam or single cam? I have a nice just-cleaned set off an 81 Nighthawk that I took apart.

SOHC ... Not sure those will fit . My buddy has an 81 cb 750 and they are not a match. Do you have a pic ?

Here is a pic of the carb in question.

And like I said , I just need an old body , everything else is good.

Thanks





DENO

Can you get the body model off the carb? I might have a spare.

and how is it broken? take a pic of the damage and maybe I can help

and the nighthawk is DOHC so that won't work.

You are correct sir .. dohc wont work . The float stem is broken on the body.

Let me get a pic for ya , Thanks



DENO

heres a pic of the broken stem ... as you can see , I have rigged it so the bowl doesn't overflow ... but it's shady as hell !

Pot metal doesn't weld very well !

Pot metal doesn't weld, period!

PM me and we can work something out; that post is 100% repairable!

And that looks to be the #4 body (furthest right when sitting on the bike), is that correct?

I'll rummage around to see if I have a spare body, but rest assured, it is repairable.

Thanks rr-rider !

The post is broken on the number 3 carb , left to right. I have heard that JB weld works just fine , but havent tried it .

What do you suggest ?





DENO

I don't really like JB weld because I've seen it fall apart while on a ride before. Ask me how fun it was to jerry-rig a cb360 in the mountains -_-

I've always created a new float post by drilling/tapping the body and threading a rod to go into it. Then I just cut to length, use a dremel to make a small flat where the hole in the post goes, and then drill. Takes about 20 minutes and I have never had one fail yet.

If you choose to go this route, you just need to do a little research on the best sizes and make sure to get a bottoming tap and matching dye. I use off the shelf aluminium rod to fix it and I usually add a dab of epoxy to the threads once I've verified that it functions perfectly.

Much more permanent and IMHO a much better, cleaner fix.

Thereagain, this also requires that you aren't afraid of drilling into your carburetors :eek:
