I just about got all the bugs worked out of my S3 - finally. I started it up yesterday after putting on new plug wires and caps. It started easily and idled better than ever. While I was adjusting the idle down a bit I noticed a large pool of gasoline forming under the bike. Darn it! The RH carb was overflowing freely. I just ran this bike last week and there was nothing wrong with the needle and seat or the float at that time.

I pulled the carb and the float has fuel in it. The needle valve is working just fine. So where do you get these things? Does anyone have a used one I can buy? PN 16031-016.

They are pretty hard to find.
If you put it over a heat source the fuel in the float will vaporize and spew a stream of "steam" from the hole to see where it is leaking.... too hot will result in the assembly falling apart. I use a burner on the cooktop.
If you properly prep it and use a soldering iron, it can be repaired. Another method posted is to use a gas tank sealer available in auto parts stores to fill the hole.

I was afraid you would say that.

I know a little bit about metal joining and the big problem is prepping the surfaces. I will try to find a used one before I tackle the repair.

Thanks for the suggestion.

I just talked to a guy that used POR-15 and dipped his floats. Swears it works fine and doesn't add much weight.

A sealant approach may be the way to go. I just inspected my float with a jeweler's loop. There are cracks in the OD that are non-circumferential. They are almost evenly spaced and there are about 6 of them. The can with the cracks is not dented or scratched. I believe these cracks resulted from stresses during manufacturing. It is the larger of the two cans - it is drawn the deepest. There is far too much damage to repair with solder IMO.

These floats are a bit odd because one can is thicker than the other one. My S3 adventure continues . . .

If you know of any used floats, let me know.

Are the floats the same as an S2?

I also confirmed - they are the same part number. Thanks for taking a look Steve.

A brief search and I found the only ones I have are in a set of complte built up S2 carbs that came off my 1100 mile S2A motor. I went with S3 26 MM carbs on that, courtesy of John Aylor. I will look more in the AM.
