Snowblower Fix

Anyone know anything about small gasoline engines? We've got snow coming, and I pulled out my snowblower last night to see if it would start. It would not. It cranks (electric starter) but does not even cough. It's one of those ones that takes a gas/oil mixture. I filled it up a couple of weeks ago (it already had a quarter-tank or so left over from last year.) This snowblower is about 3 years old and I am not proud to say I have not lifted a finger to maintain it, including emptying the tank in the offseason. Last time I used it was last winter. I'm reasonably handy with the tools, so any at-home suggested fixes would be VERY welcome, and if fact may very well save my back over the next 48 hours!
and make sure you have enough clean oil in the machine. have you tried to manually start it?

You could also, in most cases, remove the plug from the engine, reattach it to the wire, and see if you get spark when you try to start it.
You can also do this without removing the plug by running a screwdriver through the spark wire clip and holding it close to the engine block to check for spark. The same grounding precautions apply for yourself. You'll need a helper.

Response by poster: I have tried to manually start it, but the electric starter is a lot easier. I don't think the engine cares which way it gets cranked.
Clean oil is not an issue as the oil is mixed in with the gas (two-stroke engine).
Somewhere I read that putting some fresh gas directly into the carbeurator (sp?) may get it going. How much is "some"? And is that dangerous?

Before I poured raw gas into the carb, I'd try spraying some starting fluid (ether) into the air cleaner. You're asking for a fire by screwing around with gas like that.

A two-stroke engine that's not been maintained and won't start is almost (almost) always indicative of a dirty carburetor. The oil/gas mixture sitting in the carburetor the whole off-season will clog the jets, gum up the float needle seat, and block the idle passages. Unless you've taken apart and reassembled a carburetor successfully before, you should take it to a small-engine repair shop and have them clean it.

What crash_davis said. That falls into the 'fuel delivery problem'. And yeah, carb disassembly and repair is not for the faint of heart, although if you have some liquid carb cleaner (not spray) you might be able to soak them and have them work.

If it doesn't even cough with the fresh fuel in the carburetor then you're not getting a spark. Remove the spark plug and check it for deposits. If it's gummed up you can try to clean it with fine steel wool. Check the gap with a gauge if you have one. Or just replace it - they don't last long in two cycle engines anyway.
