If you found a 1/8" hose connected at one end to the motorscooter
carburetor, but couldn't figure out where the other end went, would
you plug the hose or leave it open?
What if you noticed that the hose was 2 inches long, bent 90 degrees
1/2" from the carbueretor, and cut on one end at a 30^ angle like some
string beans are cut? Change your answer?
What if you found a place with a few motorscooters in stock, mostly
junk and the second one he showed you had a very similar carburetor
with the exact same hose on it, 2", cut like a string bean at the
Do you think it's important to actually have the hose or can I just
leave the port open? I lost the hose and it was torn at the
connecting end anyhow. What's the purpose of a 2" hose versus
nothing at all?
It's patriotic. Hose say can you see!
Not sure what the function is. Might be for
pulsajet, or vaccujet. That's what Briggs
and Stratton called a couple of their carbs.
Might be why your scooter starts but won't
No hose but both with the port plugged and not. Didnt' hear a
difference. But I only tried a tiny big with it it plugged, because
that junk scooter downtown had the exact same hose. complete with the
cut on the end.
What about the 90 degree bend? Does that matter?
Maybe I can use some wire to put that in.
I looked for some hose but couldn't find any today before it got dark.
I have a ten-foot roll from HD that I'm going to return. I thought of
cutting 2" off it but rejected the idea. Then I thought of cutting 2"
off of some hose in my car, but the new cars don't have much slack.
Tonight I'll check the basement. There are two inches of everything
Sounds like a vent and they put the hose on to get any fuel that may
come out to get away from the carb (or to make it harder to get dirt
There is a similar hose on a Mercury outboard VST. It just dead ends
down in the lower cowl.

It has to be to keep dirt out. There's no sign of gas residue
What I shoudl have done, could have done in the 30 seconds the thing
was running, is put my finger on the nipple, to see if it's sucking
air in. Or a piece of paper like a diaphragm. Tomorrow.
I found lots about VST engines, but coudln't find out what VST stood
for or what made the engine VSt.
Float bowl drain so it doesn't run down the side of the engine? Some
sort of vent that would go to a carbon filter in California but
contributes to global warming in the other 49 states? Those are usually
gas tank vents though.

I looked but didn't see such a drain screw. I don't remember the
manual having anything about that. But if I have to clean the
carburetor I''ll learn a lot more about it.
I found some hose I'd bought by mistake and planned to return, so I
cut a 2" piece. I hope clear hose doesn't melt too much faster than
black hose. Of course if the engine never runs, it won't get too
If you look at the *bottom* picture of this thing,

Both in the unenlarged and enlarged views, you can see the short hose.
There's another black wire behind it, but don't let that confuse you.
The carburetor normally sits so that the brass opening, with the
throttle plate inside, faces forward, and the bottom of the carb, the
bowl, is shown on the bottom of this photograph. It seems to have
some sort of drain, so even though this isn't exactly like mine, maybe
that's how I could drain the carburetor. I'll look with a mirror
tomorrow, even if it's cold.
Yes, I saw that one on Amazon won't ship to Alaska or Hawaii, I guess
because they are too far away, or to California, because of the air
pollution laws, or to Texas, maybe because they have California-style
air pollution laws too!
An even better view of the strange hose is in this picturem, in the
top one, expanded view. Maybe it has to do with gas overflowing the
bowl? The hose points what is down when the carb is installed.

At the bottom it looks like a drain for the bowl, but I tried just now
and couldnt' feel anything with my fingers or look at it even with a
mirror. I can remove the carb but probably not until spring.
