Some saws with autotmatic oiling will leak bar oil into the cylinder and cause this. Pull out the spark plug and hold the saw so the oil runs out of the spark plug hole. Pull the starter cord till no more oil sprays out of the hole.Clean the oil off the plug and start your saw. It will smoke more than normal till the extra oil is burned out.
pull on the bail handle tape it down try to turn blade by hand with plug removed if you can move poure a little oil end cylider and spin it sevseal times put plug back in start it i think it heat siezed check oil level to thats what us red necks do let me know
From flipping the mower on it's side the top of the cylinder gets slightly flooded with crankcase oil. A good priming and a few extra pulls on the starter cord is usually necessary after this type of maintenance. You'll see a few extra puff of oil smoke upon starting. This burns off in less than a minute.
Continuous or just for the 5-10 seconds.
If continuous you may have oil seeping past your pistons oil rings or valve guides oil seals.
Check your spark plug see if they are fouled badly (covered heavily and oily) or just covered by oil and sooth lightly.
If 5-10 sec it is normal as the engine is heating up there are normally a little oil seeping past the seals.
You may have to take out the carb and get it cleaned / air-blown out. Looks like some little valve is stuck. Also make sure you are getting enough sparks at the plug tip. If you have left it long in a damp place it may take several pulls on the cord for the engine to fire-up and run. Try spraying some WD-40 into the cylinder through the plug-hole. Then pull the cord again. After a few pulls remove the plug again, and put like a spoonful of clean 10/30W engine oil into the cylinder, and keep pulling the cord until you see some smokes at the exhaust. If the engine fires up and run a few minutes, but stops later. The engine might be out due to incorrect oil/fuel misture.
Assuming the engine is burning oil and not leaking it out, the most common cause is wear on the piston rings. Somewhat continuous light smoke indicates rings. A puff of smoke when starting up the engine or pulling away from a stop sign indicates worn valve guide seals.
A puff of smoke when you start up indicates worn valve seals.That's why all your work didn't fix the problem and it doesn't show a code. It's a pain in the --- job that requires some specialized tools so I guess it depends on how bad it bugs you,if oyu want to fix it.
verify condition by spraying some starter fuel in it.it should start and die if its a fuel problem.
if it still does nothing start checking any and all fuses.if all the fuses are good take out a spark plug and verify no spark.
if no spark check the ignition module.
it might be able to have it checked at autozone for free.but you will have to remove it.
