Thanks for the reply! Except for the hesitation to come down to normal idle, everything is Great. Idle is good after about 20 seconds and at anytime the transition is flawless...no midrange gurgle whatsoever..smooth as can be! Maybe I should live with setup I have,. I am 80 years young and can really get those needle valves screwed up and have to go back to factory settings. I ALWAYS discard the spark plug that comes with the engine and install a CM6 plug. Thanks again.
