Homelite Bandit line trimmer, maybe 50cc. Many years reliable service.
Starts on choke per instruction manual. Even after it warms up, it won't
take gas. Increased throttle results in decreased rpm. I have to keep it
on half-choke to trim the weeds. It is recommended to run it at full
throttle after it is fully warm.
Any idea why it won't throttle up?

With these things and these symptoms the most likely
culprit is a fouled carb. Or a clogged, collapsed, or
leaking fuel line, fuel filter, etc. You could try spraying
carb cleaner in it. If it's the carb, mabye a 30% chance
that would solve it. Otherwise, if it's the carb you have
to take it apart and clean it and get a rebuild kit.
The need to use the choke to keep it running is your clue. Look for anything
that is restricting flow of fuel to or in the carburetor, or anything
that is letting too much air in somewhere else. Gummed up carbs are common
in small 2 strokes. Sometime engines with lots of run time will start leaking
at the crank seals enough to let air into the crankcase and lean out the
fuel mixture. I've seen the same happen when throttle shafts get sloppy too.

Most of these things use the same basic Walbro carburetor. They just
get jetted differently.You can usually find a new one on the net for
$50 or so when you find the right number.
To clean it take the big screw off that end and the 4 screws off the
other and remove the parts. Get a can of carb cleaner spray and shoot
through all the holes. Then slip a small piece of fuel line over the
spout on the can. Slip it over the brass port in the center of the
carb throat and back flush it from there. Put it back together and try
