 |
|
I have been working to find out why my CHTs are so high, and now have dynon EMS-D10 with 6xEGT and 6xCHT.
I am not sure whether the problem is cool ducting, or mixture….
Here are my EGTs…. All in degrees C
Climb- range from 675-776 across cylinders
Cruise- range from 607-695 across cylinders
CHTs are peaking at 182 after a climb, with OAT of around 10.
Does this tell us the carb needs new jets, or not?
Thanks,
-Carl.

Carl-
I notice that you have a post on the Europa forum also. Is your Jab in a Europa? If so, I have some suggestions.
