Hi, What are you 601 pilots seeing for cylinder head temps in your plane with the 3300 jabiru . My rear cylinders are running 340 and 325 and no matter what I try I can,t get them down any farther. Thats what I saw today with a temp of 70 f and a nice 300 miles around the Blackhills of South Dakota. I am afraid as the summer warms up I am going to have heating problems??
