Octane, thanks for the superb photographs/guides on how to revamp a full set of carbs - what with these and Randakks DVD, it should be easy-peasy :)
PS This site is a goldmine of information - thanks to all who contribute.

I realize this is kind of an older thread, but I had a question;

I have plans to re-finish my carbs in non-stock style. Plenum, carbs, CV slides, intake runners and all powder coat.

High-temp black wrinkle or black chrome powder-coat. (BC on the polished bits)

Would anyone here be interested in seeing an extension (of sorts) of this kind of thread that went into detail on what to block, how to prep, etc.?

I won't go into detail about the carb rebuild, that's been done very well by Octane... According to Randall, the video doesn't cover refinishing. (I haven't seen it) so maybe an addendum-type thing would be useful to someone who wanted to powder-coat or more likely, paint, their carbs?

Yes, yes, yes and yes.
Please Deek. Do a thread about it.
That would be great.

This is for the Hampster. I cut my snorkel when I put in the accell coils. Not enough room. I couldn't tell any difference in the way the bike run good or bad. Plug color the same and everything. Go for it! Cutting the airbox like octane did is a different story. I cut mine and had to go to 125 secondary jet and shimmed the needles 1/2 mm. I tried going up on the primary with bad results. The bike actually lost low speed pick up. The needle shimming done the trick. Thanks to Randakk AND Octane. I can't give these guy's enough praise. If they were paid for the knowledge they lay on all of us, sureley they would be millionares!! :lol:

I have the Randakk kit and new stock seats and float valves. One thing I noticed in my teardown was the black plastic cap over the choke rod on mine is missing and a piece of stainless wire has been rigged there. Do you have any pics of how this was supposed to be originally. This looks suspicious to me...

I am rebuilding my carbs off a 1976 Sulfer yellow Gl that I bought new on Dec. 31, 1976. Have had the carbs off a couple of times to clean out plugged pilot jets, would'nt run at idle without the choke. Fowled #3 plug last time I ran a 100 miler. Decided to overhaul carbs before this season of riding. Started to take off carbs when I noticed white Plastic on top of polished dome blown out and broken. Do I look for another complete top or what. Who sells the plastic covers? thanx d4bell

I think you can epoxy some nickels in there. I've also read you can cut the tops from a plastic paint can top. The important thing to remember is not to clog up the vacuum port in the top. If you look for it,... you will find it. No need to use different tops.

What do you do when after you rebuild, install, balance carbs and you find out that two of your throttle shafts are leaking air through the carb body and will not allow you to set the air mixture screws properly? i.e. always running too lean which means you cannot get a good idle.

I found this problem when I did some "sniffing" with starter fluid and did a small direct shot at these shafts, and carbs 3 and 4 increased in RPM but 1 and 2 did not.

Is there anyway to rebuild this area in the carb body? Are there bushings there?

Some folks have used felt to seal the shaft.

Yup,

That sounds right to me, somebody else got some at a fabric store.

Thanks Whiskerfish and Cookie.

The felts from the trumpet sound about right. Probably have to cut them down a little.

The felt from the craft store also makes sense.

I made a die to punch out the center hole in 1/16th inch gasket paper and use the brass cap ring to mark out the outer diameter.

I checked out the fit and shaft interference on my "learing aid" carb and it fits and lets the shaft rotate freely.

I have some felt and will see if I can make it out of that, too.

I will take my carbs back out and give it a go in about a week. Got some honey dos first. Will let you know how that went.

Thanks again!
