Check for spark at the plug.
If the engine has points and condenser . check to see if the points are good.
If electronic ignition, then it is likely the ignition module is the cause

Just replaced air filter, fuel filter, and plug. Ran good for 10 minutes then started spuddering and died. Restarted right away and huge cloud of blue smoke came out. It spudders for a minute and dies

Blue smoke is oil. Have you checked you pcv? (Pollution control valve) it usually runs from one of the valve covers to the airfilter unit.

Hi I have a Craftsman Lawn Mower 225 and i bought a 40w oil and put in it and it started leaking and ommiting huge white smoke. what should i do?

Hi Manny First thing is Drain all the oil back out. You have most certainly overfilled it. Try and get as much out as you can from the same place you filled it from. Leave it tilted back until it stops running and then put the mower level for half an hour. Check the oil level now and clean the spark plug and replace it. There will still be oil in the air filter due to over filling. Only put oil in one egg cup at a time until its below max on the dip stick. Run the mower for 20 minutes and burn the smoke off. It may smoke for a few times but thats ok.

My mtd yard machine (leaf blower) started billowing white smoke. I shut it off and now it won't start again.

First check the oil level. If its overfilled correct it. Then remove the spark plug and turn the engine over. Replace the spark plug.
Start the engine. Use a prime ( squirt carb cleaner into carb) if you need to. It may start smoking again. Thats OK as long as you know there is oil in it and you dont hear any strange noises. Let the unit run for about 5-10 minutes and see if the smoke clears up. Once it quits smoking stop it and check the oil.

Our Husqvarna YTH2148 mower has been in the shop twice and we can't figure out what's causing black, sooty fouling of the spark plugs.

Hi, change the engine oil. It has become contaminated with fuel. Also fit an inline fuel tap and turn it off whenever the mower is not in use. Basically the carby has leaked fuel into the engine oil, the engine then draws the fuel vapour from the oil through the crankcase vent into the carby creating the problem you have. Regards Phil.

Tractor will not start unless you poor gas into the carburetor. When it dose start it let out a small cloud of white smoke I have changed the fuel filter,spark plug & air filters on the tractor. It has...

It sounds as if your carb. needs cleaned, the fuel line is obstructed or the fuel filter is stopped up. All of these will prevent fuel from moving throught the carb. to the engine.
