What does 4 mix mean on the Stihl weed eaters?
O.K. pea, I'll give this one a stab. It's a 4-cycle engine that runs on 2-cycle fuel. It meets the more stringent EPA regulations regarding emissions. The reason a normal 4-cycle engine wont work very well is that it requires an oil sump and operating it at odd angles, like our trimmers, would starve certain moving parts of oil.
Thanks for the information. You told me more than I knew. Sounds like something that would work pretty well.
2 stroke with valves. Much more torque. And yes they work very well.
loccutus hit that nail on the had. Our gas hedge trimmers are 4 mix. Had to ask the dealer.
My dealer (Shindawa, Kawasaki, and Maruyama trimmers offered) told me that by 2007 companies will no longer be able to carry 2 stroke engines. I think this is absolutely ridiculous, considering nearly all the atmospheric problems are caused by naturally occuring events.
Anyway, I don't know if he is right or not, but he did seem to be very knowledgeable. Shindawa and Stihl make the 4 stroke engines (with oil - mix). I am not sure if or what other companies offer these.
I didn't know they had more torque. Thats pretty cool. You say its because of the valves?
Don't forget the "Harley" Sound!
Then we will all have to be policed by special interest groups acting on behalf of the State / EPA offices to see if we are carrying any "illegal" two stroke equipment in our trailers. When will it all end??? Freakin' tree huggers...<a href='http://www.smileycentral.com/?partner=ZSzeb008' target='_blank'><img src='http://smileys.smileycentral.com/cat/15/15_4_125.gif' border=0></a>
You can operate these 4 cycle engines at any angle all day long.
when they go to 4 mix there going to grandfather the old 2 strokes made before they set the rule right?
