Fuel and AV Gas

[kim]

Last weekend I forgot my fuel drum and had to borrow some gas of my mate.
As he uses AV Gas I wasn’t sure how it would go.
The first tank was about 50% AV Gas and ordinary pump gas.

Bike started and idled much better than normal.

Second tank was straight AV Gas and was running very rich, but idled and started excellent.

However I could really only use the first 1/8 of the throttle as it would start to splutter badly. Still had a good day riding, just had keep hooking up in higher gears.

WFO seemed OK, but it took some effort to get if up there.

Since I got home I have changed the pilot down from 45 to 42 and its now 40.
It starts and idles much better than it used to.
Air screw seems to have much less effect than it uses to.

Here is the question:
When running AV Gas would you expect to change your jetting significantly ?
And would you expect to go leaner all the way ?

As I have just found out I can get AV gas for the same price as super thru work and the airport is only 2km away, which have a 24-hrs fuel bousser.

With the idleing and starting alone it seems very worth it to change to AV Gas

Also I run 2% mix.

Any comments most welcome on AV Gas.
