4 mix questions?

[Training Wheels]

Hello all!


First post...I've been wondering for some time why are 4-mix engines either all on or all off? I can't seem to figure it out. I have some basic knowledge of small engines but get stumped by this question. I'm a little dense so it may take some explaining in simple terms.

Try posting this in the chainsaw sections, there are more gear heads there.

Early Stihl models had crap throttle response, they've gotten better. Still not like a 2-smoke but way better.

Never had a problem with throttle response on my pole saw. Lay it on the wood, pull the trigger, it cuts wood without complaint . Sounds kinda snappy accelerating not under load, just not high rpms. I prefer this kind of power for pole sawing.

Have a Kombi that is 4 mix, works just fine. Wouldn't guess it's not 2 stroke.

Was that to do with carb?

My 4mix trimmer and blower have excellent throttle response. I often run the trimmer at part throttle when trimming against chain link fence.

I suspect your unit needs some adjustment. It's probably either carburetor or valves that need adjusting or maybe a leaking valve cover or impulse line.
