Power loss will come form oil temps out of control. Anything over 160 on the oil and power starts down. The mixture runs right into that rotor and it is at about 350 degrees. So much mass is lost to expansion before the port closes.

 

Hi Lynn,

 

For years, you’ve told us about power loss with higher oil temps, but I’m pretty sure this is the first time you’ve say WHY it happens.  It seems so simple that I’m embarrassed that I hadn’t figured it out myself :-) 

 

Thanks,

Rusty (taking building productivity lessons from Tracy <g>)
