Hi!

I have a plane that has the fuel-tank right behind the engine ... I haven't had any flameouts, but I think the engine (a Saito .91) is not receiving enough fuel when accelerating to full after I've hovered for about 3 minutes ...

Will installing a Perry Pump help at all or should I keep things simple and not mess with pumps ?

what are the symptoms to make you say that its not getting enough fuel after a hover? Also is this something that richen up the high end could fix?

There is a VP-30 and the oscillating pump. Not sure if you can use the VP on a 4 stroke?

the 20 is 2 stroke
the 30 is 4 stroke i ran the 30 on my satio 180 great product.
i will be running the 20 on my 2-os-160

I havent had the great success with the perry line that others have had. I started using Cline and have not had a problem. It is a "diffrent" set up from the others. I am now running Cline on a Saito 1.8 a OS 1.6 and a Moki 2.1 and love 'em. I would recomend it.
