nope on the web site but my experiences with homelite are not good. always
hard to get parts for (at least for me) You can check the following
1 with the sparkplug removed take a flashlight and look into the cylinder
make sure piston is at bottom dead center and look on the cylinder walls for
scoring, if you see scoring the cost to fix will be high you may want to
exchange it. If you cant see through the spark plug hole you can also remove
muffler to check cylinder, this is also a good time to make sure the exhaust
is not plugged up.

2 make sure the gas is fresh old gas wont burn and unit wont run, rule of
thumbs if gas is over 30 days old from when you bought it get new gas and
start over. if you do have old gas drain it from unit and re try. you may be
lucky enough to get it going with out taking the carb apart.

3. the old plug sparks when against the motor test only tell you it has some
spark not whether or not the spark is strong enough. get a proper tester
from a local shop they are not very expensive and they take the guess work
out. In a pinch one may make a tester by breaking off the tip from a old
plug to increase the gap it has to jump it will be somewhat better test then
just seeing if it will jump 0.025" or so from a normal plug. also for the
cost of a spark plug if any doubt about it replace it.
