 Interesting idea. The oil pressure on my JH takes about 15 seconds or so to drop below 10 psi when I shut off the engine. The oil flow down from the cylinder head is pretty slow, probably to keep the pressure up. So what you are seeing sounds about right.

My question is how you expect to be able to start the engine after it has been sitting for awhile. When mine has been sitting I have to turn on the ignition and let the fuel pump run for a few seconds to get the fuel running to the carbs. But it would also take a good 10 seconds or so for the fuel pressure to come up far enough for the fuel pump to come on in your design. So how to you manage to start it in the first place with this?
