The cg is currently at 4 1/8". This is 5/8" foreward from factory spec. When I fill the tank in its current location it moves only about 3/16 inch foreward.

Another quick note.............when I removed my cowl last nite to run the new fuel line, I had to also remove my needle valve extention. So I counted how many turns open I was before removal. AMAZINGLY it was only 1.5 turns open. I KNOW it is filthy rich at this setting, because I could see my smoke trail well against a cloudy dark sky. And it sucked that 16 oz tank dry in 10 minutes.

Its been my experience that usually a rich setting is more than 2 turns, up to 3 before it starts to four stroke. So knowing this, it is my speculation that the 1.20 develops alot of tank pressure, hence the 1.5 turns open.

So I believe (and hope) that the 1.20 will develop good enough pressure to deliver the fuel another 3 inches properly. I will do some nose high testing on the ground before I make this assumption though............. and AFTER I get a few more break in tanks through her.
