Great pics Charlie 'n Bryan, I had the Peterbilt Swan in mind for my 149, bit I've got a real dilemma, I have the 149, but according to the engine sticker on the blower housing, i have a K301, not the 321 that is supposed to be there, or the K341 that /I wold love to have, some day maybe, i haven't cracked the engine open, so i havent been able to dust off the micrometer to measure the bore and stroke to find out... what'll I do? (dramatic i know) Oh and it's NOT a AQS or a Quietline, or a new replacement, its the "Original" yeller Kohler... Glen
