Folks, I have an older Craftsman lawn mower that I can't get to start.
I do get a good spark, so I'm assuming that it means a clogged
carburetor. Is there anything that I can pour into the tank and allow
to sit there that might help dissolve any old varnish? Thanks in
advance for your suggestions!

You could try draining any old gas. Re-fill with fresh gas. Remove the air cleaner
and squirt 1/4 tsp or so of gas into the carb. Does it fire up now? If so, but it then
dies, repeat the priming with gas a few time. It may clear itself out, and run.
