13 years ago
I have Problems with the adjustment of the temperatures of the EGT of my motor Rotax 912 ULS
This motor operated in the city from Cochabamba to an altitude of 8500 Feet
At this time that motor is operating in the city of Santa cross that is to an altitude of 1370 Feet
In the city of Cochabamba they operated him with the needles in the position 3 and according to their operator they never had reading of bigger at 750° in the EGT
Now in Santa Cruz we have made all the adjustments from the carburetor to the suitable ones for it manufactures, but the temperatures of all the EGT surpass the normal parameters (up of 880)
All the other parameters CHT is inside the normality
We placed the adjustment of the needles in the position 4 again and the EGT normalized 2,4 the 3 this inside the normality but slightly bigger at 2 4 but the 1 you ascends at 880 to low alone 550 RPM at 834 to 4900 RPM
We take out the spark plugs and the same ones denoted that we are with an excessive rich mixture because the color of the same ones is dark (black)
In the same way in the test of magnetos the RPM falls more than the normal thing 500RPM and there is a strong vibration.
We would like to see the possibility that if some friend can help us with this problem
