Bing leaks

[Vegasrandall]

After much swearing,dripping,tweaking and whatever I replaced my floats to try and stop a drip.it worked and just out of curiosity I weighed the old versus the new float. New float was 12 grams,the old float weighed EIGHTEEN GRAMS. In my book that's a whopping humongus difference. Has anyone else weighed theirs?

I've never weighed any, but if you put in new floats (and you should), I would then turn my attention to the fuel line.
Is it the cloth braided line?  It is the worst for long-term hold-up-ability, but it looks cool.  It is also hard to see where the leak is located.

If you do have the braided line and you don't know when it was last replaced, replace it, too.

Snowbum did a lot of testing and found float weights in the range 12 to 18 grams. He said the 18 gram floats almost sank.

Just throwing this out there, Bing has molded floats available to replace the standard foam floats .

Bing part number 35-310 .

About $37US each

+1 on this. When I got my bike back together after rebuilding the carbs, the left immediately leaked. I thought it was the floats, so I rebuilt/cleaned it a 2nd time, with no change. Paid closer attention and noticed the braided cloth fuel line was weeping gas badly but I couldn't see it under the braided cloth. Replaced with new, unbraided line... problem solved.

I'm a sucker for the cool look of the cloth covered fuel line myself, so I just treat it as a consumable and replace it every 3-4 years.

I also like the cloth line, and haven't really found anything that works better or lasts longer. For one, it's 7mm which is an unusual size here in the US. Our alternatives are quarter inch which is too small (a bear to get on)and 5/8" is too large (requires a clamp). It seals well and is easily removable. And on top of that, it just looks right.

I don't know of any fuel line that's good for more than three or four years, so just because yours finally deteriorated doesn't mean the cloth covered line is junk.

Yeah, I like the braided as well, and to be honest, the right carb is still fed with the braided line. I just replaced the leaky section to the left carb. I plan on replacing with braided... I just wanted to get it up and running!

With the close proximity of the fuel lines and ignition wires, I want any and all gas leaks to be immediately visible. Just plain rubber fuel line for me.
