Just checked mine this morn . #1 #2 and #3 all maxed out at about 165 . #4 was around 180 . Two years ago it was 140 on the first 3 and #4 was 150 . Guess working this tractor did it some good ? Gotta wonder what a fresh engine rebuild numbers would be ? Should say this is a 149? gas Series 1 . Thanks !!
