now does he make the crank shafts. is there a center support int eh crank case for the crank? also what does he do for the timing? do they both fire at the same time or what. i am intrested in finding otu abotu that engine cause it is pretty slick.
If you type in Sachs-Dolmar in your search engines.(I use google) you wont find much on chainsaws anymore..but a ton on some place using cylinders in this same fashion for model airplanes...single cyl..multi's--- take a look! pretty cool stuff!

Below is a link to a address of large model racing engines and some of the planes that use these. Some use 090 stihl heads to make a boxer twin. The 2100 x 2 engine is 180 degree timed.

How do they seperate the crankcases on those things? Or do the two cylinders scavenge off each other?

The engine has the front and rear as individual crankcases.
Another site offering husky based engines. The 7.3 is of course the 3120 based engine. http://www.taurus-engines.net/

Interesting thread, this...
When I was a lot younger I was pretty interested in model airplanes and boats, especially for the cute little motors. Then I grew up, got interested in things I could ride in or on, and forgot about the RC world.
Just so happens that I had some time to kill at a mall today, and was thumbing through an R.C. magazine engine buyer's guide issue. Them boys got some interesting stuff...Ignition systems that make our chain saws seem like a lawnmower engine, with programmable advance, advanced carburetion, etc.
I know power costs money, but where are the saw makers? I know echo has the slope advance system, but where are the others? Are chain saws left sucking hind tit?
