Lawn mower starts, but that's all it does.

Good advice testcase - I would also recommend using some Seafoam in the gas to help clean up varnish problems http://www.acehardwaresuperstore.com/sea...tml?ref=42

I use it in my power equipment to keep it running good and it has also salvaged more than a few "dead" yard sale buys.

I was ready to rebuild the carb on my current tractor, and after a few tanks with Seafoam it now runs fine.
