AV8TOR, You know...I did read about that using a extra gasket is bad like you say. I guess it exposes the internal threads that have sharp edges. What can happen a edge can glow and cause pre-ignition in some engines that run full out, kinda like a truck going up a long hill! Well we are into the New Year now! I sure hope it is a good one?? A local club near Muskegon always get together and have hot food and open flying. I guess the temp may get near 30 degrees. Just may go if I can talk my Granson into going! Yup we fly togeher a lot. Take care, Capt,n
