Thread: Do I have an 066 Mag?

Been thinking about this and I really don't know. I see the shadow left by a Magnum sticker on the top plastic. It's directly adjacent to the 066 nameplate. Has the dual port muffler, older style cartridge air filter, and semi-clear gas tank.

But...it also has the redlight ignition. If not for this, I would have no problem with calling it a Magnum.

I have no reason to suspect that all these pieces are anything but original.

My parts list shows the main difference being the muffler and spikes.

Thanks, Chris Bean

I could be wrong, but it is my understanding that the 066 was the only saw that came with the redlight on it. Also, the 2 port muffler makes this a true Magnum.

With regards to the 066, I am working on one of the older models.
Is anyone aware if any of the 066's varied in compression rates?
I put together one yesterday and noted that at TDC the piston just barely contacts the top of the jug when I used gasket cement, so I fabricated a head gasket instead and it's alright but it sure has lots of compression.

I forgot to add that the jug has no compression release nor any provision for one.

Gypo,

I would consider mine an older 066 because of the LED, and I used the high comp. base gasket with zero problems. Without a gasket, never tried that.

Chris- yours is the magnum. All the red light 066s were magnums. The high and low compression models were dependent on arctic or non-arctic. The arctic models used the thicker base gasket.

The red-light indicates the governed ignition and these were only made during 1991-92. The ignition supposedly topped out at 12,500 when new but as the rev-limiting ignition ages it tops out at less rpm.
