Pull the carburetor and clean it for staters.Be sure to change oil any little bit of moisture in the crankcase will let it smoke white by seeping by the valves and piston rings.Also put a little small amount of dry gas in the gas tank to rid all of the water that may have been left in the tank. I some of this will help you.

The smoke is oil going in to the combustion chamber, will have to check for broken rings or piston. also if the tractor was stored in a position that the oil would run to the combustion chamber it will do that untill all the oil is burn

your Tractor is probably burning oil bad. check the oil, there could be too much oil or too little.

SOURCE: Craftsman mower with 20hp B&S Intek won't start/run

That throttle cable issue sounds like it may be the culprit. the cable housing (the outer casing for the wire throttle cable) may not be anchored correctly. Which may be allowing you to move the throttle without any change at the butterfly control on the carb. make sure the cable housing is anchored at both ends.. by the throttle control and at the carb area.. That may be your problem... hope it is that simple...

Honda gx620 on golf cart occasionally bogs down & blows enormous cloud of white smoke from exhaust.gas getting in oil also.runs great until this happens

What ussually causes white smoke to come out the exhaust is oil being sucked up in carb. Typical causes are too much oil in crank case or PVC valve. Or really bad piston rings

Toro zero turn mower with Kawasaki 691v 24.0 horse motor starts cutting out and smoking after running for about 20 minutes.

Check the oil to make sure you don't have gas getting in your oil. If that's not a problem then you may have a leaking head gasket.

I have a 1986 GMC P/U Truck with a 305ci. It has a quadrajet Carb that has been rebuilt. The problem I have is that it wants to "Bog" while going down the road like the A/C came on or like you...

You may have a leak vacuum or part. Check hoses and then fittings. A switch is changing or temp sensor maybe be an issue also. Check engine codes also

Trouble starting and a lot of black smoke at startup

Could be. Black smoke means too muck fuel or not burning properly. Also make sure your oil is not over full.

My truck runs fine at times but then it will bog

Hello there:
the way you are describing it it is sounding like the fuel filter is started to clog and might need to be replaced.
you may also want to look into a tune up i.e spark plugs and wires and rotor cap and air filter ect ect ok?
best regards michael

Mower starts then it smokes

If you spilled any oil on the engine, it will smoke for a few good minutes until it burns off.

Or, you may want to check the air breather. It may be dirty.
