I remember someone posted regarding a hairline crack running down the'vent-tube' in the float bowl. Anyway to fix or is it a matter of replacing the whole float bowl? Symtoms include constant fuel leakage.

Thanks all.

I had the same problem.
I couldn't get the tube out without breaking and couldn't find a good used one so I sealed the crack with JB Weld. It's suppose to be fuel proof.

Try a rebuild kit that includes a new float needle and seat. These wear out, especially on carbs these old.

Scott,
Do you still need those carbs I sent?
If not you can send them back rather than pay....assuming you didn't "modify" them in any way

Would'nt JB Weld seal the "vent-tube/drain-tube" also?
The quick fix that was recommended to me is.....
heat shrink tubing. Temp fix obviously.

Leaves the top of the 'tube' open.

But, if y'all say the JB will work I'll do it rather than hunt-down a new float bowl....

it wont seal it if you just smear it up the side. Noone said to fill it up with the stuff.

JB, i'll keep the carbs, you still do paypal? i have your address.

Fill up the float bowl with JB right?

Just kidding...Thanks going to try it now.

...And I am still interested in the 450 stuff. Just got a new truck.

Scott,
Paypal would be fine...address still the same.

Don't want to contridict anyone but.... the vent is there for a reason. If you have a float problem it lets the fuel run out the vent instead of into the cylinders and from there into your crankcase.

For instance, if the fuel valve was left open and fuel leaked by the seat and there was no vent it would fill up the carb, then run down the intake into the cylinder, then past the rings into the crankcase. Then you start your bike with a crankcase full of 10w-fuel oil...which is really bad for plain bearings.

It also allows fuel and escape during hard braking, cornering, foaming etc rather than the level going way up.
