I've had Subject trimmer for ten years, and of late it has been hard to
start. I've probably yanked on the cord about 80 times this morning, and
a few times it sputters and dies. I've had it in choke and run
positions. Usually run gets it going. The outside temp is 62F. The
little transparent fuel clear bulb has lots of fuel in it, as required.
There is a bubble in it that may be 1/2" in diameter. I used it the
other day for 30 minutes.

How to proceed?

My friend's trimmer wouldn't run so we got the manual cleaned the
carb, took out the needle valves, sprayed cleaner into the holes,
put the needle valve screws back in using the manual as a guide
for the number of turns open from fully closed and fueled it up.
It cranked and ran on the first pull.

I blew his mind once when I ran a weed eater on compressed air.
