Hi everyone,

Attached you can see the photos of the combustion chamber of my JJ1400. I am experienceing high temp problem at high RPMs particularly after 130K. I have checked everything: 1. Balance is perfect 2. vaporizer tubes tested with propane not much difference 3. Startup perfect temp not over 450-500 C. 4. Bearing conditions are OK. 5. Compressor clearance is even perfected with sheets of hysol layers.

So I believe there is only one problem left: Poor vaporisation!... Am I correct?.. I see that the vaporiser tubes are way too short and away from the combustion front cover..I would appreciate some input. Can I find vaporiser tube circle similar to MW 54 ?. Does anyone have spares or any contact for supplying?.

Thanks
