(yes, I know that's what it's for). Started running very rough,
missing, won't idle. When stopped, gas drains from carb drain hose.
doesn't drain while engine running. shut gas off and stops draining.
with gas off, will drain if drain screw opened (so gas in bowl). will
drain with drain screw closed if gas is on. starts easily. what the
heck is going on??

Two different tubes and you don't understand the function of each tube.

The carburetor drain tube (it is has one) will come DOWN from the
bottom of the float bowl. If it always leaks, the drain screw leaks.

The float bowl vent tube will come UP from the float bowl. If fuel runs
out of that hose, the float valve is leaking.

You can sometimes squirt Berryman's B-12 Choke and Carburetor Cleaner,
of STP carburetor cleaner or Gum Out carburetor cleaner down the
gasoline hose that comes from the gas tank and it will dissolve most
gum and varnish that make the float valve stick.

There is also the possibility that the float is set far too high

FB,
Thanks for the kind response. As it turns out, the rough running was
from a torn vacuum line. The gas draining was from a stuck float valve,
probably crud in the gas. The float chamber has an overflow stem that
drains out the same line as the drain valve, so in actuality, it is the
same drain line. Thanks for pointing out my lack of understanding.
There's lots of things I don't understand, but your lack of friends is
not one of them.

Yeah, well, you can pick your friends and you can pick your nose, but
you can't pick your friend's nose...

Factory service manuals are way more informative for the basic stuff and
and way less insulting for the basic stuff than what your going to find here
in
this group.

You will find that in any of the technical/repair groups, from the
automotive
to anything else, that people don't have much patience for the basic RTFM
questions. Usenet isn't a substitute for a $25 manual that contains the
exact
specific information for your bike. Where Usenet works well is assistance
with
problems where the manual falls short.
