Ruined carbs - help needed

[Nessism]

Hi Pat,

The 34 mm carb pieces are the same size. Unfortunately, the pieces I have are the mirror image of the piece you need. I think there are RH and LH oriented pieces so to speak and the ones I have won't work for you. So sorry, but don't give up hope. Post those photos in the parts wanted forum and someone here will have a carb body you can take that piece from. It's easy to change, trust me.

back with some more questions about these carbs that are slowly driving me up the walls. Excuse the length, I like pictures and detail

Well I purchased a carburetor body from a '82 GS650Z - it was mentioned earlier in the thread that the 650 carb would work with my setup [BS32SS]. I checked the Mikuni stats page on basscliff's site and seemed that simply changing the components into the new carb body would solve the problem, but boy was I wrong...
The parts arrived today and I cheerfully started to transfer all the parts from the broken body into the new one, thinking I would soon start the engine for the first time in over 2 years. As you would have guessed, I have once again run into a wall

After replacing the jets and float I put the float bowl on..*gasp*....wait a minute something is not right here, it doesn't seem to make contact with the gasket...
After a couple of minutes of observation I pulled out a ruler and started measuring. Guess what the problem is yet? you got it! the new "choke circuit fuel pickup tube" is 4 mm longer than the one on the original -guess size does matter!!!

here is a picture, because they tell more than I ever could - right is the original :




so right now if I put the float bowl on, it will make very close contact with the gasket but I think all the pressure is put on the brass tube - not good right ?


so my other option is to take off the adjuster piece all altogether and replace it with the functional one. But here is where the other problem starts - after all these consecutive failures I am slowly losing all confidence in my wrenching ability so I'm not quite certain if these roll pins are in my league. I don't own any roll pin punch tools - are there any alternatives to taking them out? how would I re-install them? (if they can in fact be reinstalled)

Here are the suckers that are giving me hell:
Broken:



Replacement:




I'd greatly appreciate it if anyone could provide pictures or videos on how to remove the roll pins or suggest a way to use the current setup?

Cut the tube off to the right length. Use a dremmel or a hack saw and don't break it. It will work as long as it can suck fuel because there is a jet in the float bowl that will meter the fuel.

Mobius, have you repaired this yet?

If not I have the answer for you.
Find a nail you have around the house close to the same size as the pin in that linkage. I am guessing a framing nail will do without looking closer.
The nail needs to be a hardened nail, not aluminum or zinc.

Cut the tip off as flat as you can.
You are not trying to win a beauty contest on how flat the nail is

Support the bottom side of the linkage and leave the pin hole exposed and drive that puppy out.

I have used said method in a pinch on many a lawn mower pulley and it has worked every time.

If you are not sure you can do this, go buy a punch of the same size as the pin and drive that thing out.

Small ball peen hammers work best for this.

I have a full rack off a 700 if they'd work by switching jets, etc.

What Bill (chef) says is a logical solution. Also, using a nail or a drift pin would remove that roll pin. Gently reinstall it into the good body. With these minor bumps you are experiencing it is a given. We have all been there at one time or another. One thing is to do it right the first time and take your time in doing it. This isn't just a pit stop. You will be riding soon, it's only May. Bob

The nail method works great. If you have a bench grinder you can trim a fatter nail to get just the right diameter.
