Carbs reassembled (with pics)

[Detman101]

Well, following the guide on this site I have reassembled the carbs for this bike minus the broken float post. It seems to hold well with just the pin in the one side. Bouyancy and the stiffness of the pin will hold the float in place I reckon.





I noticed that the inside of the tank is rusty. How gas can cause rust I'll never know...but there is a fuel filter on the main supply line so I figure I'm safe.


I am not sure how to hook the carb-set back up to the bike because I have no manual but I'm going to give it a shot tomorrow.
The linkage for the throttle cable goes here right?



I wanted to start out with a fresh set of carbs but no one has any for sale. So I'll make do with what i've got for now.

I went out to the bike and tried to turn on the accessories(Lights, Dash) with the key but it didn't turn on. I really hope its just something disconnected under the seat cause I'd hate to have to go back to where I bought it and rip someone's neck off.

Well, I guess I'll read some more and see if I can get this bike figured out.
Thanks for the information and advice everyone!!!

Yes, that is where the cable hooks up. The cable sheath fits onto the arm, and the cable itself extends to the lock point.

I would revisit the float mount. You may be right about the stiffness, but if it flexes a little, the float may stick, and will not be able to do its job.

You have the carbs off, so now is a good time to do the job right.

The broken piece can be fastened with fast-setting epoxy....JB Weld seems to work well. When you put it on, be sure to run the float pin across, so that it fits into both mounts, and ensures an accurate position.

It's been JB-Welded before by some shop the previous owner took it to. It all went soft and fell off again in the carb bowl. Then the owner traded it in on a new bike.

If the float sticks after this I'm going to have to get the post welded back on somehow. That is assuming I can get the wires and cables hooked up right and get the bike started.

I still don't understand what supports the carbs. These things are heavy while empty. Adding fuel would be another 1/4 pound probably. What holds these things up? I really wish it were still fall...I get home too late to do any work in the daylight. If the bike were lighter I'd wheel it inside the house. That thing weighs a ton!! :?

Darnit, there was something I wanted to ask but now I've forgotten again...

Okay I remember now.

I set the Fuel/air screws to 2 1/2 turns out. Is that a good setting for the stock carb-setup on a 1981 GS750? Im just going off of what my VN750 is set at and want to make sure that this will work on the GS.


Thank you,

It is best to do the repair properly the first time, it saves a lot of unnecessary work, The carbs are supported by the intake boots and the air box. JUst remember IT will NOT run properly until you reinstall the air box
