Hello all,

I am experiencing an issue at startup with one of my engines.

Problem: The engine starts with no problem, but goes to excessive high RPM's, then settles down. I am very concerned due to the fact that the oil mixture hasn't had enough time to lubricate the cylinder and reach operating temperature.
I have replaced both the high and low pressure pumps and thoroughly cleaned the VSTs.

Is there an automatic choke adjustment or may there be underlying issues.


Thank you for your consideration!
Mark
