Reply #1 - 01/09/16 at 07:31:13 If you're leaking fuel from the vent tubes, your float valve isn't sealing properly in the carb. Disassemble, clean, check condition, reassemble or replace needle and seat depending on condition then reassemble. Always verify float height when you change the needle or the float. Check your oil for gas.

Those vent tubes need to be open and operating.....they are there for a reason (to vent). I think it is a bit weird that they extend so far up - but perhaps the idea is that if you tip over and the bike is upside down...the fuel will not flow onto the hot cylinder head.

Well, yes....they can be soldered....but it is not easy.

You can drill the hole, and drain it, then when you try to solder it back up the expanding air inside wants to blow the solder out of the hole....or the cooling air wants to suck the solder inside.....or you heat it up too much and unsolder the float from the mounting arm. (You also have to be sure you soldered up the leak that let the fuel get inside).

A wimpy soldering tool means that you have to hold it on longer, creating the problems Dave describes. Clean the area, apply flux, get solder on the tip of the gun, stick it on the area, hold till you see it flow. If it sucks in /blows out, no biggie, Now it's tinned. Now the solder just needs to stick to solder. A damp sponge cools the tip
The cooler tip has less resistance
Lower resistance increases current flow
That increases temperature

Cool it
Stab the tip into your flux
Apply solder to the iron
Touch the spot

If that doesn't get it, id be surprised.

If you don't already have soldering tools, probably ahead just buying a float.

I've been having carb issues for the past week.
the engine doesn't like a certain rpm off idle... sometimes.
backfires, crackles and pops... awesome and on command.

pulled the carb and found a hole in the diaphragm.

found some glue that's fuel proof (pliobond) at ace hardware.
used it last year to revitalize an intake duct on an old bike.
just slather it all over and it's like new... well at least the cracks are gone and it's flexible again.

unless anybody got a better idea, I'll use the pliobond to fix the hole.

Haven't had it in the bike yet, but it appears to have fixed the issue.
just fill the hole with it and wait for it to dry.

Is that a big problem? What it can do?

If they are really tiny - it might not hurt anything as long as they aren't letting so much air pass through that the piston isn't raised against the spring pressure.

I would be tempted to put a tiny amount of RTV sealer or Superglue on the holes.
