Same here I love my Husqvarna 4 stroke 224L.
I can not find anything I can not cut , tall grass ,all the way up to small trees. It does not use much gas ,I cut 2 today only use 1/4 of a tank.

That is the only thing keeping me from jumping all over a 130 right now.
I understand why 4 mixer's don't rev smoothly and a Honda 4 stroke rev smoothly .

A 4 mixer' s as fuel mix that goes in and out of the crank case that makes a odd pressure in the intake .

No, it's in the throttle control/trigger assembly's design. The blowers and other 4 mix stuff are very smooth throughout the throttle control's range. There was a post by a mechanic on here last year or the year before that explained it in detail, but I can't remember what the thread was. It isn't that the trimmers don't rev smoothly, because they do. It's that they are hard to feather up and down smoothly. The engines run great. I love the sound of them. If it wasn't for the feathering issue, I'd be all over a 130.

That's interesting to watch, but it doesn't have anything to do with what I'm talking about. The high/low pressure doesn't have anything to do with why Stihl 4 mix trimmers jump up like they do. If it did, it would also affect all their other 4 mix engine equipped machines, and it doesn't. Their 4 mix blowers don't have that trouble- only the trimmers. The blowers can be feathered very smoothly all the way from idle to WOT and back down. I remember the guy I mentioned earlier illustrating how/where it is in the linkage of the trigger and throttle cable system on the trimmers.

My guess is that these 4Mix blowers, while being essentially ~twice the displacement/cc's of the 4Mix trimmers, are under more of a constant&increasing load due to spinning an impeller - thus moving a lot of air throughout its RPM range.

I think you are right smaller engines have more fuel problems than bigger engines do. I know a lot about engines, threw the years I been in my Dad's logging as I work on saw to Big diesel trucks to my days has a small engine mechanic and RC airplanes of ever size scents 1990 and my airplanes are the only one at the flying field that run perfect.
