I've had Subject trimmer for ten years, and of late it has been hard to

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?

When my 36 got hard to start the carb was fouled from storing gas in
it and I had to get it cleaned. Pull the plug after trying and I bet
its wet and flooded, so use dont flood it if possible. Either-
starting fluid should help but the final solution might be a carb
cleaning, a new plug might help, when the plug is out ground it and
pull the cord to see if the spark is good.
I suspect it is wet, but I can't find my spark plug wrench. I think it
looks like a socket wrench with a lever arm protruding from the side
about 8".

Cranking it without the plug isn't dangerous is it?

You can test the ignition system of a 2 cycle trimmer by using
compressed air. Put the rubber tip of a blow gun or spark plug
adapter attached to an air compressor tank and the engine will
run on 50psi air. You pressurize it and pull the starter rope
to get it started and it will putt merrily along. You can see
if you get a good spark from the detached plug wire while the
motor spins. It's no mystery if you understand how 2 cycle
engines operate.
