my Cozette No 4 delivers only a maximum of 2 psi unde only at revs over 4000 min-1
How can I tell if he is no longer delivering or licking pressure?
I dare not dismantle and open it
the pressure gauge is recalibrated.

Perhaps someone can help me?

Is the explosion valve on the inlet manifold working properly and screwed up?

Is this an old post, Thomas, you posed this question a while back, and the problem was resolved and you were pleased with the car's new found performance.
Wasn't it the valve stuck open last time, as suggested by Charles P?

If the blow off valve is leaking badly you will be able to feel it leaking with your fingers when the engine is running.Or the vanes could be sticking in the rotor if there is a lot of oil in the fuel or sitting in the blower.

The pop off valve is ok I checked it two times.
Too much or wrong oil in gasoline is a good idea.
I switch to fully synthetic 2-stroke oil.
A compressor engine makes the hobby vintage car not easier.
I do not know any engine specialists so I ask in the forum.
thanks for your help

If You think there is too much oil in the fuel I think I would drain the tank then refill with just petrol and run it carefully for a few minutes to see if you get any more boost.If not you might have to look further.
Depending where your blower came from it should run on 1 or 2% two stroke oil.
A blown car is a bit of a challenge to keep running well but there is no substitute for that extra torque!
