OMVL R90e vaporiser set-up

[bluesj]

Hi all has anyone got the set-up info for an OMVL R90e vaporiser they would willing to share with me? I have just fitted one to my RR but I never got a lot of info with it.
Cheers Simon

To get a pretty good setting without test gear -
Open the screw valve (power valve) in the delivey hose to around 75%
open and follow first part of set-up as below. ie. The almost stalling
procedure.
Then set the throttle to cruising revs and HOLD throttle position
STEADY. Screw the power valve in until the revs just start to drop off
a little. Then open the power valve again until the revs pick up. (If
the revs pick up as you wind in then keep screwing in until you reach
the drop off point.)

Re-adjust idle.

Drive the vehicle. If lack of power then open power valve 1/4 turn at
a time. If fuel consumption is too high, then close the power valve a
little at a time. Don't overdo the economy, you don't want the mixture
too lean.
