As it turns out, it seems Claude might be onto something. Pump pressure of the Xareltoo engine is 1.1 bar. Not far off what Claude says it should be. I may tweak it a touch sometime, but for now i'll leave it alone.
I also checked the number 2 engine in the Valiant. That was reading around 0.75 bar, so I richened it until it read 1.1 like the other one. 1/8th turn on the reg equals approx. 75-80kpa. I haven't flown the Valiant since adjusting it, so it will be interesting to see how it goes. Hopefully tomorrow.
I would think this would apply to any DZ engine. Maybe not the exact numbers but the process would apply. Now to find a small pressure gauge.
This is great information!!

EDIT: Claude in your opinion would you ever need to go above 2 bar in pressure? I'm thinking having a gauge that is as close to the max pressure seen will give greater resolution for future adjustments or confirming pressure???
