Porting a unicorn

[jmssaws]

Al @drf255 wanted me to make a hybrid out of his 064 so he sent it to me,I had him a cylinder and a damn good one but once I started porting it is noticed plating missing above the exhaust so we was out of a cylinder
I have a few real good ones and one that's the best I've seen or heard of really,I've always wanted to port it so I'm using it on his saw.
The unicorn cylinder stock is
99.5 122 78 020 squish with a gasket
And runs very good stock
I cut 040 off and got
103 125 80
Never had one at 103 so I gotta try it where it is just to see how it runs.

I like the sky and clouds. Makes it look like GOD ported it.

Not sure who would want a cylinder like that!? Just plain junk.

What is a unicorn cylinder?

066/660 cylinders vary a huge amount with timing.
You want the best timed cylinder you can get for porting. They just run better.

Tree Monkey should be given credit - he is the one who figured out the unicorn cylinder on the 066 660.

Alright. The question to be answered is who will conquer the unicorn?

Left be seen but I know who will be riding it Long Island style.

I think "harness" would be the correct terminology...
