I wouldn't worry about that at all. Just start it, if you can. You may have a carb full of varnish to clean first.

If you are the cautious type, drain whatever oil you can when it's cold, fill with fresh oil, start and warm up the engine, drain it again and fill with fresh oil.

First thing you do, check the oil. Chances are it's condition is not too bad - you want to make sure there's enough in it for that first pull. Second, Remove any old fuel. This is a lot more serious than old oil. Replace with fresh gas with a good dose of auto fuel injection cleaner. Assuming you get it started, be prepared to change the oil after a thorough warm-up - use SAE 30 HD or the 30W lawnmower oil you can find at home centers, hardwares, etc. Most engines of this type take 18-20 ounces.

Thanks for the follow up guys.

I am a little anal-retentive with oil changes, "cheapest insurance you can buy" as my grandpa says.

Most of my equipment I run HD-30 oil in, and I've actually employed the fuel injector cleaner tip before. I picked up a wisconsin-robin engined commerical snapper from the side of the road. Worked great for a couple of years, then the 20+ year old engine started to really lose compression. Just bit the bullet and bought a Husqvarna 7021R with the 160cc Honda, very nice.

Thanks again guys, and any more advice / ideas / tips you care to offer up I'll take 'em!
