I've only tried two remote NV's, one from an OS .29X (old Max III speed engine), and a bone-stock OS .25LA. I didn't like either, for starting problems mostly. I think the .25LA one leaked a lot of air, so when I choked the engine and got the fuel up to the venturi, the fuel would run back away from the venturi by the time I put the igniter on.
The .29X deal was about 55 years ago, so I can't remember much except that it went away very quickly. For both, I recall that the NV response to adjustments was painfully slow and totally unacceptable. The .25LA unit suggested to me that the Magnum and ASP remote unit is one heck of a lot better made, and that is difficult for me to admit.
As Randy said, that's not the way to avoid adjusting for tank height. Moving the uniflow tube inside the tank is the only option, other than changing relative height between tank and engine. Not many will move the engine instead of the tank!
