Hey Frank - 1 and 1/2hr already. Dang!!!! Bet she sounds sweet!!!!! You need to get the idle down to about 1000rpm and see how smooth it is. I wondered about the back pressure making a difference too. I've got the larger style muffler with long exhaust pipe. Not exactly sure what it was for but closest I could find to an exact replacement at the time I did mine. Jim Steele picked it up for me from a dealer closing his doors. Supposedly had an IH part number tag on it but could never cross reference it. Funny thing was, it was the exact muffler that was on the engine when I got it. It has the curved inlet fitting like the quiet style for the 14hp and under but those don't have the long exhaust pipe. I had to use a nipple on the block instead of the "S" shaped Kohler fitting (but the nipple was already on my block as well). I believe it has a smaller outlet than the Kohler fitting but not exactly sure. All in all I wondered if this back pressure helped to smooth the engine vibrations along with the stock balance gears I left in. I remember at that time I even got the "special Kohler tool" for re-installing the balance gears. Kind of a funny shaped Y tool, but worked pretty slick. It's now in Jim Cabot's collection of special tools, but of course you didn't need it. Since mine is a show "King" (169's have to be male gender) I didn't use the David Kirk point saver. Now, what's holding you up from the rest of the assembly!!!!!! I don't know how you can wait for the 1st drive. Those Kohler fumes at idle and that breeze blowing thru your hair when you're running down the road. Dang it - I gotta get mine out of storage!
