Hello Scott
I used fuel tank clunk with foam (as shown on picture).
Once foam broke and clogged durit. Since I use 2 tank with normal clunk. It's work very well.
To set up pump, I use a manometer installed as shown on picture.
It's awesome to control and adjust pressure pump.
At the iddle or when engine running only with starter, pressure must be 1,2 bar.

Every few weeks my mouse pointer starts hovering over a buy-it-now/add-to-cart button for a DZ200cdi but I've resisted the temptation so far.
Oh, and I don't mind if you claim the Ferrari as your own, we all know F3A pilots are closet millionaires from the prize money and endorsements....

Wow, that makes moot any argument for the high pressure fuel line needing to be "rigid".

Hello
No problem with original fuel line after pump if there are clips.
At the beginning before adjusting pressure was about 3,8 bar and there was no leak. So engine was very too rich.
Ferrari belongs to friend of mine. He flies with a Calmato. So I have a cheaper Renault but a YS 200 CDI on my pattern.

Hi Claude
Where did you get the info about the pump pressure. How much adjustment was required to get it down to 1.2 bar. Seems strange that YS don't set this pressure correctly prior to shipping their engines.

My second 200cdi in the test stand ready to run and then running.
Reg left as straight out of the box, main needle 1 1/2 turns out and the break in needle 1/2 turn open.
Very rich, but will start leaning off and closing the break in needle after 2 tanks.

Hello David
Friend of mine who is fond of mecanical (he was a Renault Alpine competition mechanic) did differents tests on stand (same as shown by Scott).
To decrease pressure I turn counterclochwise the regulator screw.
At iddle when pressure is 1.2 bar ; at max rpm pressure is about 1,8/1,9 bar.
Knowledges has been shared. So in France those who have CDI (170 to 200) proceed in this way.
When there was issue it is very easy to do and know if pump is correct or no.

Hello Scott
Which plane for this magnificent engine, may be new Excessbip ?
Is it possible to get a picture of régulator (profil) to see position of screw ?

This engine will be going in my Valiant, which is my current backup plane. As far as I know the Excess Bipe is electric only.
I leaned the regulator 3/8 turn from the factory position. I'm pretty sure that is the same as my other engine. The screw is 0.25mm out from flush.

After 5 tanks of fuel through on the test stand, the engine is running well. I let it idle for 2 minutes, it then throttled up without any hesitation at all. RPM peaked at 6900 and after a few seconds it settled at 6750. I'm very happy with that.

Both my planes are now 200 powered.
it has always been my experience, that a YS tuned on the test stand, will not be the same when in the plane. My second 200 proved no exception.
The engine was idling and transitioning perfectly in the test stand. Once in the Valiant it was running very rich, but I left it at that for the first flight. After landing, I checked fuel consumption - 500ml for P17. Way to rich.
So I played with it for awhile and ended up with the reg 3/4 turn leaner. Idle and transitioning is good, but may be just slightly rich still. Main needle is around 1 1/4 turns out.
It was almost dark by this time, so will have to wait for further flight testing.

Claude's method of setting pump pressure is very interesting, so I thought I would check the pressure of mine. Mind you, as it is running so well, I had no intention of adjusting it no matter what the pressure was.
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.

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???

Not to need to go above 2 bar.
We ajust pressure at the iddle (engine with starter or running) about 1,1 / 1,2 bar.
Max pressure is an other information to know is pump is correct.

Hello
Friend of mine who did tests told me he adjusted about 1,2 bar. The best way is to test.
About 15 flights with 200 CDI very reliable even a sealing problem with the o'ring seal at the silencer inlet.
Engine runs well but there is a leak about 2 flights et plane is oily.
Have you same issue? Which o ring do you use ?

Hey Claude,
I only use the Hatori #178 O ring. I've found this one lasts much longer than other brands I've tried.
I have 119 flights on mine now and it's running great. I have had one problem that has reoccured twice, but hopefully I've got that sorted now.
Have you any idea what area the oil is coming from? Like which part of the engine has oil on it?
Scott
