Carby Gas leaking where fitting attaches to carb

[gearhead222]

Dear Fellow Motorheads-I tired Teflon tape and it's a no go. The fibre washer with the nipple is shot. Should I try a small amount of Hondabond and toss the fiber washer? This leak is so bad that the bike was empty when I went to ride her!. Thanx for any feedback-Gearhead222

You should be able to get fibre washers from an auto accessory store.
Either way, it's good practice to turn off the fuel tap on 2-strokes when the engine is not running, otherwise it's possible for the crankcase to fill with fuel if the needle/seat is leaking.

Thanx Stevo! I researched this and discovered that a rubber O-ring might work. Used Teflon Tape and the rubber O-ring and it's not leaking!-Gearhead

Good one. Just keep an eye on the 'O' ring. Some types swell and distort when in constant contact with fuel.

it shouldnt be leaking anyways...

if the fuel level in the bowl is correct, it sits about 5-10mm clear of the fuel... fuel goes through the hole in the centre...

me says look closer...

Thanx Head! I adjusted the float level once- a real PITA!-Gearhead

you are 100% correct, if it is leaking, i would look for a crack in the carb where the fitting threads into it.(as long as the float level is set right.)

Switch the gastank petcock off before you get to the house..motor should be starving for gas just as your getting off

i did this once and ended up with a 10km ride with most of it uphill...with half a cup of fuel for assistance...

Try turning it off when you're almost home, as Tedd meant, instead of 10km from home.
What did you expect???

Personally, I agree with Tedd - NEVER leave the fuel petcock 'on' while the bike is parked.
As I mentioned earlier, if the needle and seat leaks the crankcase can fill with fuel, not desirable.
This is separate to the actual problem.
All the talk about float level and so on means nothing in this situation. There's a reason there's a fibre washer originally fitted to the carb's fuel inlet tube. Regardless of float level, if there isn't a fibre washer fitted, fuel will leak. The fuel doesn't sit obediently at the float level all of the time. It is splashed and shaken around as you ride, and will cover the base of the inlet tube during (RH) cornering. I've had that leak in the past, on a few carbs, on a few different types of bike, (not MBs). The float level was set correctly in all cases.
