Question about Craftsman 17.5 hp 42 in. Deck Lawn Tractor - CA Model
Hard to start if engine stops on top of compression stroke acts like gas on piston when it starts it'll smoke white than stops last time used had a miss under a load new plug oil filter cleaned
White smoke in a small engine is oil. Oil in the cylinder will create too much pressure for the engine to achieve compression. Make sure the engine is not getting fuel into the oil and thinning the mixture (literally smell the oil... gasoline and oil smell nothing alike, if it smells like gas, it is). If this is the case, the carb is leaking fuel into the engine, thinning the oil and causing the oil to leak past the rings into the cylinder head, through the valves and, from there, into the exhaust to burn off. Black smoke indicates a direct fuel issue in a small engine, white is oil based.
