gas probs with Stella

Post by Mike1nw »

2005 Stella 2T
my friend's scooter.

First, it wasn't getting gas. I took apart the fuel cock and removed the sand from the valve. :roll:

Second, now it leaks gas like a Yugo. From the carburetor. Runs all over the floor. It's not coming from the tank.
Took it apart, getting a new needle valve.
Is that the likely culprit?

I noticed that gas sort of dribbles out of the gas hose. But it's easily more than one gallon per hour, which is about how much the scooter uses. Or am I wrong here?

Starting with the float needle valve is a good place to start. Is the float floating? Make sure its not damaged or hung up.

The volume of fuel delivery out of the petcock is pretty slow.

I've also seen the rubber tip of the float valve swell up and deform when exposed to those "pour-in miracle fuel system cleaner" type additives. The rubber that they used for it does NOT play well with solvents for modern vehicles, especially if someone uses the whole bottle that's meant to be used with 20 something gallons in a car, vs the 1-2 gallons in a stella.

Thank you!
Gas leak was a defective mini hose clamp on the carb bowl.

BUT the float was also sticking a tad.
The needle was in great shape.

The gas flow rate (a dribble) bothered me, but the thing runs great.

I know you’ve solved this now, but I’d like to point out that I’ve had fuel leaking after a rebuild before, only to find that I didn’t tighten the screw over the small mesh fuel filter.
