Problem was resolved by installing an overhauled carburetor from Kelly Aerospace , BTW make sure you get the carb with any mounting ports for instrumentation, ours a JPI carb temp probe. First one had a plugged hole that could have been machined but we didn't want to mess with it. Kelly took care of us by sending one with temp probe port already machined in after we returned the first one we got. Our old carb (an O/H) had been installed seven years ago. Thanks for the help!!
