thoughts?

Based on advice from a very knowledgeable machinist in the family I have begun stalling all my two strokers with the choke instead of killing them with the means provided, kill switch, etc.

The thought is that this way they get a blast of fuel/lube on the parts as it quits.

May yield longer service life? Opinions?

Interesting thought, don't see how it could hurt.

I had an old Kawasaki dirt bike with a non-working kill switch that I had to do that to in order to shut the motor off.

Didn't seem to hurt it - rode it almost daily and had it for years.

Doing this would just be a "feel good" move, nothing more. The internals are already getting a blast of fuel/lube as you shut down with the switch. All you're going to do is make the machine difficult to re-start because you flooded it.

I always do this with my 2 stokes.

I also do this to my 4 stroke snow blower, the logic there is to keep the bowl as full as possible since I don't know when it will be used again.

Actually that hasn't been the case at all. No problems restarting on any of them. Using cheapo 90/10 gas with the factory supplied synthetic oil mixed in. The fuel has a bit of Stabil in it.

Just make sure you have an extra plug and a plug wrench in your tool kit.

I'd say all you are doing is shortening the length of your spark plug. The thing doesn't have to be firing to suck in fuel.

Maybe I'm missing something here, but any 2-stroke I've ever owned has a kill switch that kills the ignition (spark) for engine shut-down. There's no fuel/oil starvation going on by killing spark. Like said, snuffing it out w/ the choke just soaks the plug and loads the muffler and atmosphere with raw fuel/oil.

Please explain, how does the float bowl contain more fuel if you use the choke to shut the engine off? The float bowl is gravety fed in most cases and what you claim defies logic!

+1 to all that

I think you're better off with the kill switch. Normally most of the fuel flashes into vapor inside the crankcase leaving the oil behind. By using the choke the internals just get a parting shot of solvent.

I idle down for a short cool down under the theory crankcase heat and high vacuum vaporize the fuel and load the case with oil.

Exactly. As soon as you hit the kill switch, combustion stops, but the engine continues spinning for a little bit. While it's spinning, with the choke open, it's still sucking in oil from the carb as if it was running.

Thanks for your opinions guys, I appreciate the input.

No issues restarting, so no fouled plugs. And everybody knows a two stroker is ALWAYS filling the atmosphere with unburned fuel!

And unless you're holding the throttle open when you kill it (which I always do) you aren't getting very much oil.

To each his own.

If the choke is closed and engine is drawing vacuum the fuel will be pulled it to it's highest level. This will stop when the engine stops completely and carb will remain full and wet.

The main reason though I do it on my snow blower is so I know the choke is already on when I go to start it in the dark. I don't have a light in my shed.
