I am guessing maybe oil too rich, but don't know much about engines. It almost starts or starts for a few seconds then bogs down and leaks smoke for a few seconds....

2-stroke
Tom, You didn't give much info, but if it's a 2 stroke it could be fouled plug or an oil-rich mixture. Old fuel is often the culprit these days with the addatives. Pull a sparkplug and take a look at it. If you just tried to start it and it looks wet, you're getting fuel but maybe too rich (it's also possible you need a hotter plug). If the plug is really dirty and leaves a lot of residue on your hand when rubbing the anodes lightly, again either too rich a mixture or a too cold plug range. You also didn't mention what color smoke-which makes a difference(at least on auto engines). Multi-cylinder engines also have a distributor and cap which can collect moisture inside and provide alternate(wrong)paths for the electric leading to the sparkplugs. Hope this helps..

White Smoke
White smoke can also mean water in the fuel. On a 2 stroke the water is usually in the fuel. Head gasket leaks that could let water in will usually prevent the motor from starting at all. Fuel today has a lot of alcohol in it, and can contain a lot of water mixed right in with the fuel. You won't see the bubbles of water on the bottom of the tank because the alcohol mixes it right into the fuel. If the compression is good, the spark is good, and the fuel is getting to the engine, check the quality of the fuel. Always use fresh fuel with your 2 cycle. 2 years ago this ment fuel less than 2 or 3 weeks old, now it means fuel less than 1 week old. The alcohol they add to the fuel will let the fuel soak up water right from the air.
