I am interested in some tips/tricks to get a little more out of my 066. Its bone stock, does what I need it to do when I need it. Like anything, if I can get a little more out of it I would like to. My main objective is not to burn it up, but I know there is power there that is not being used. Thanks in advance and interested to hear what you all have to say!!
Is your 066 equipped with a dual outlet muffler?
Easiest mod is to port the muffler. You can buy one or modify your own just make sure you still have a spark arrest screen in place if you do it yourself. Did this with my climbing saw a 330T and it made a huge difference. You may need to adjust your carb afterwards.

Fixed it fer ya ;)
Does it have a green cylinder gasket?
That is a 1mm gasket. Replace it with a black metal 0.5mm gasket for improved compression.
If you decide to fit a dual outlet muffler, you could use a 0.74 jet. That is the one which comes on the Brazilian 660 Magnums.

That's exactly what my 1992 "Canadian" 066 Magnum Arctic Red Lite is setup with. Notice the 77° F thermostat controlled heating element on the carb! And the best starter grip ever from a Jonsered 80.
Oh almost forgot, ha ha ,if you look close you can see the Oregon 50AL .050 .404 chisel bit chain

Thanks for the replys!! Gives me some ideas
They respond VERY well to porting. I took the base gasket out of mine to get a squish of around .025", manipulated intake and exhaust timing a bit and increased the area of both. It had just under 200psi compression and pulled a 28" bar with absoluted authority in any hardwood. Just grunted and motored through anything.
