Hope you got paid well for that!
No the exhaust starts to open at 96 degrees of rotation .Stock was 101-102 degrees .Did you use a mandril, of a lathe to cut the base? Are you saying that you raised the exhaust 96 thousandths of an inch from where the top of the port already is? You also said that you did something to the intake. Finger-porting, or just opening-up a hair.
We've got a foreman at my shop who only runs 038's. I don't know how he keeps finding them. It's an awsome saw.
If I can find it again I'll bump it up in the chainsaw section
Aren't you enjoying that Hobb's, Stephen?
The step up from a Porty to a heavy duty lowering device must be fantastic, with the stuff that you are constantly dealing with.
