preivers,

I did not mean to step on anybody's toes here. All I see is some people saying that it is good to shut them off this way while others say it isn't. All I was asking was why all of these, when it is much elegant to kill the spark. This does not cut the fuel off and hence the oil. The only merit of killing the engine with the choke that I can see, is redundancy. You can use it when the ignition kill failed, which BTW never happened to me. Like I said, I am new to gas planes, but I used chain saws and weed eaters for years. I never shut them down with the choke, not on the first, not on the last run of the day, and I still have to destroy one yet.
Enough said, time to move on..
