Are all your other guy’s using the Projet gas-valve as well??
Cause I did, and it sticked like hell, and needed to be lubricated a lot to work. And I finally dumped it. I had it dis-assambled some times, and I as was surprised that it ever could work: There were practically no power in the electro-magnet! Only a tiny movement, with close to no force.. I was tempted to rewind the electromagnet, but as I have external gas I saw no point in risking to overload the Projet ECU-controller by pulling more amps.

If it works wiht silicone oil, I'll might give it a try, but i doubt it..
