Filter and chainsaw.
Göran, @Woodrunner a few questions, I talked to Jonas, he had made a fiberglass filter and let the gas in on top of the filter.
I tried the same thing, but get so little resistance that almost everything from the unit ends up in the filter, quite large pieces, like sugar cubes.
I’m afraid that these pieces can burn holes in the filter, what do you think?
Next question, I’ve completely renovated 242xpg, how do you usually run in new saws?

Hi Jan, i don’t think the bigger pieces do any harm, as long they don’t hit the fiberglass directly, and have enough space in the bottom of the filter.
I built my filters double-walled, and acting as a cyclone at the same, and it works well. The Chevy draws a lot of big pieces, up to twice a sugar cube.
As for the chainsaw, i use a very little more oil (0,5-1% more) and slightly more fuel (maybe a 1/10 more open on h/l jets, as long it runs good) this would be enough on 2-4 fuel refills.
This above may be unnecessary safe, the most important is no longer periods of full power, like cutting a log lenghtwise.
Ordinary firewood cutting, in “normal” dimensions is the best. Just common sense 
About giving it more fuel, this is mostly for carrying away heat, it should by no means get more oil or fuelt until it smokes, or build up carbon.

Ok, put the cyclone back, the carbon stays on top of the filter, the car had a little better power without the cyclone, but no big difference.
Thanks for the advice about the chainsaw, I chop in the forest with this, but the boy usually has it on the woodpile.
