Different length carb slides?

[TDC]

I have been having fueling issues with my 350 so I took the carbs off again to check them over again. I had rebuilt them early last season so I wasn't expecting there to be much wrong with them. Just wanted to check the float heights and make sure a spider hadn't mad a nest in one.

While looking them over good I noticed that one of the slides didn't drop as far into the venturi as the other. I made sure they weren't haging up at all. Then I measured the them with a caliper and found one to be about .093" shorter than the other. Now, I'm thinking that isn't right. Maybe the PO slapped two different carbs on it from two different bikes? Don't know why I miised this before. Probably explains why I could never get things balanced very well last spring.

The other thing that bugs me is if I set the float height to the recomended 19mm, it seems as if the floats are just about bottomed out on the carb body and way past the fuel level deposits on the old floats. It won't pour out of the overflows set like this but the over flow nipples are a little moist, especially if you are kicking on the starter enough to throw you back out, like I have.

Any suggestions or crast comments are welcome.

I have been looking at the OEM parts pages at bikebandit.com and it looks as if the slide part number may have changed part way through the K3 series. They list one part number for '70 K2, both for the '71 K3, and the other for '72 K4. I don't know what might have changed about the part. The PO had a number of 350's around so I wouldn't doubt there was a bit of mixing going on. I'm going to see if my local cycle salvage yard has a set of slides or carbs for me.

OK, now I have a new used slide that should be the right length to replace the short one. I'll see if it works.
