I missed out on this thread so have to bump.
I bought a first year 1991 066Mag RL -32" brand new in '92. I replaced it with a brand new 2008 395XP-32"in 2010.
Last spring I sold the 395 and rebuilt the 066 with new OEM main bearings, seals , intake boot and lines. Original P/C and rings still pump 175 PSI. Still have the original diaphrams in the carb and still runs perfect

The Arctic heated carb may have helped their longevitity.
As bottom pics show I got the 066 Mag Arctic down to 15lbs 5 oz (15.31 lbs) from 17 lbs. Made it into a 066/064 hybrid by installing a 1986 064 flywheel, rewind housing, top cover and brake lever. Just replacing the dual outlet muffler front with a standard front cover saved 8 0z.
A diet of 5 more oz will get the 92cc old girl into 14 lb territory.

Will do that by gutting the muffler, installing the early 1986 064 air filtering setup, deleting the heavy walbro compensating carb top cover and a few other 064 tricks like 4mm screws installed with Heli Coil.
Now rebuilding a 1995 066 flat top with first year decomp. It will sport the older 066's dual dogs, 28" b/c and dual outlet muffler.
Both 066s will stay in my tree service until I retire the business.
Even though I only ran my 395 for 8 years, the 20 years I did run my 066 hard for proved it is my most reliable 90+cc saw.
The only good I got out of the 395 was it made a great milling saw. But for doing treework 066 much more user friendly.
More pics of both 066 saws to come.
