I used one of the chech governors, starts with a Z that whirl wind sells and it fit a 6a without the recess. Most said it could not be done. A 4 is certainly a different animal but the moral of the story is to measure.
The prop governor for a 540 runs at a different ratio than one for a 4 cylinder. Make sure you talk to a governor shop to determine if yours will work on a 4 cylinder without modification. The shop I talked to said most could be modified to get the gearing correct but be aware you will incur cost to have this work done.
Vans sells the materials and plans to make this cut-out - no need to re-invent the wheel.

Also, I am concerned because I have a Christianson inverted oil system, and think I may have a lot of stuff "in the way" for govenor installlation...anyone have this combination on a completed 4 ?
Thanks!
