Small Engines (Lawn Mowers, etc.): troy blit 4cycl trimmer, wasp nests, spark arrestor


Question
it worked fine last tuesday, today it wont start. seems to be sparking, gas is moving through primer bubble.  gets hot when a crank it a bit.  just wont start????

Answer
    These trimmers have a bad track record in my book, but you might look at a few things.

Look at/in the muffler, make sure there are no wasp nests blocking it, or the spark arrestor screen is fouled.
On the top is a valve cover, where you can see the rocker arms
and adjust the valves, remove the cover, and watch the rocker
arms move when you pull the rope.  See if they both are working.
Check those things out, and tell me what you find.
