Right The fueling strategy and lubrication system have nothing to do with the design of the engine with regard to generation of power through the firing cycles. To be sure, four stroke has many more parts than a two cycle, but the design of the 4-Mix engines is four stroke.

Got to make sure people know to run MIXED gas in them, since people always think 4 stoke = straight gas.

4 Mix = 4 stroke engine that operates on 2-stroke fuel for lubrication. There you go simple as that!!

I've never ran mixed gas in my 4 strokes...

Would it hurt if I ran a tank of 40:1 or 50:1 mix through them?

No, you can't do that. Stihl has the gas pass over the valves into the lower crank case, to lubricate everything.

Buying a 4 stroke was the best thing I ever did. It's quieter, less finicky, sooo much more torque. I hardly have to touch the throttle the cut through most stuff. I'm sure its not recommended but with the brush cutter attachment I can cut through a 1" sapling with out much trouble.

With the roto-tiller I can throw small rocks out of the ground and cut through roots. Def worth it to go 4 stroke.

It's a 29cc so it is heavier but well worth it

Why do you ask?
You mean you run mixed gas in a 4 stroke that has separate oil like Honda trimmers? For one tank, I don't think that would hurt. I won't make a habit out of it. I dump the older mix into my cheap mower on and off and is still running.

I don't see any thing that can damage the engine, just extra carbon build up. Something you should be able to clean with Sea Foam if it is just one tankful.

Now the opposite will be bad......If you run 4Mix or C4 with no oil in it......then you'll be in deep dodo.

I agree for a tank or occasionally it's not going to hurt anything, the only thing it will do is probable make it smoke more than usual, I've run in my push mowers on occasion and they actually run pretty good, but as Alan said I wouldn't make a habit of it.
