Having a bit of trouble with my 5port after putting in a turbo head button. It's not idling well and keeps flaming out. I had to richen it up with turbo head to keep temps in line. I used a rb6 plug, then tried a rb5 and an os6. Left same shims in it that used with standard head. I'm running trinity monster horsepower 30%, motor has just over a gallon on it. Any help would be appreciated.Pooldoc
