Any bright ideas why my snowblower won't start?

[TrogL]

38. Finally got it to start

Was going to work on it again when I discovered the shed door was frozen shut. Dumped 1/2 a bag of ice melt in front of it so it would work its way under the door. A day later I was able to wrench the door open, but cracked it in the process.

All the bolts were rusted. Some of them were really deep set. Went to three different stores before I found a set of deep small bore sockets such as 1/4". Got the rest of the bolts off, then had to wrestled the plastic cover past the spout. The cover eventually cracked in two places but I got it turned around enough to get at the spark plug. Found out I didn't have a socket to fit it, was already to simply give up and go buy another snowblower (saw a nice one on sale) when I decided to drive back to a pawn shop I knew had tools. Got a proper sized spark plug socket and went back to the house. Got the spark plug out with some effort and had a look at it.

It looked really corroded so I went at it with a wire brush. Checked the gas - it didn't look too bad so I thought I might as well give it a whirl. Started instantly, ran really, really rough so i let it idle for about 10 minutes until it smoothed out. Then I blew a bunch of snow, letting it sit each time it started running rough again.

I'm going to go out and buy all new bolts to replace those that are rusted and have fallen out and put the fluids in as recommended above.

Comparing it to the ones I was looking at and thinking about buying, the one I have is a really crappy, stupid design. I'm never buying a Briggs and Stratton branded appliance again. They make good motors but they don't know shit about workable design. I should never have had to go through that much agony to change a spark plug.
