Full rpm on a Farmall M is a couple hundred less rpm than full rpm on a Farmall h is. In short, an m does not scream like an h will.
If you happen to have a friction type handheld tachometer handy: Then it is not so easy to use it on the engine itself due to clearance issues, but it is very easy to use a handheld friction tach on the PTO shaft with it engaged. At full rpm you should be seeing somewhere around 600 rpm on the pto shaft at wide open throttle and no load.
FWIW: I have some investigating/adjustments/pin slop/spring tweeks to do on an ole m that I am fixing up for myself as it is only seeing about 500 rpm on the PTO shaft at WOT. My h is spot on at 600 pto rpm at WOT at no load. Of course this 600 rpm drops some under a load and then gets you in the neighborhood of the proper SAE spec of 540 rpm that equipment operates at under load.
