I have a thought. To all of us who have had v-max engine trouble. I would like to know if you have had engine trouble what kind of fuel have you used during this trouble. Not just hard to tune v-6's but breaking rod v-7's as well. I would like to see if there is a common denominator..I am not trying to say that there may be a bad fuel source but maybe just the wrong kind for the finiky norvel.. Thanx for inputs.. Alan
