Re: [DOG mailing list] CHT during warmup 110 degrees Celsius at static RPM 1200

[Jarek Steliga]

Laurie,

Thank you. No, my Dimona was not pointing to the wind and there was no wind
of note at the time. It took between 10 and 15 min to reach that
temperature. I will look at CHT during the taxiing. Thankfully the CHT
never exceeds 180 degrees on take off.

I enjoyed being Karen for a bit despite the gender issue :-)

Regards
Jarek

Ian,

Thank you for sharing. I will try the same.


Regards
Jarek

I find to warm up run for 5 Min then shut down for 5 to 10 min and then
warmth goes through whole engine.  At next start up it will be warm with
oil gauge registering. A few of us have done this for a while and works well

Hello,
I tweaked the metering needle in the carb and am not sure if the CHT is in the 
acceptable  range. The ambient temp was around 20 deg C.
What do you think?
