anyone have any ideas on how to put a temp guage on a c-144 hinomoto? dont want to drill and tap anything if i can help it. mine has a block drain line right behind starter, and was thinking of putting a tee in it with one side being guage, and other side being drain. being low in block, would this give an accurate reading or not. dont really want to have thermostat housing drilled if i can keep from it. also, does anyone know the correct hp of this tractor? i have heard anything from 14 to 18 hp, and tractordata lists as 18hp. what would the pto hp be, and how many engine rpms would i have to run to achieve 540 pto rpms? thanks
