 That the oil pump takes a long time to prime is a warning sign of imminent failure, but I think I have heard anything up to 30 seconds from cold is "ok". The old worn out engine in Ms Jensen takes on the order of 30 seconds to prime in cold weather, but that engine is done in most respects.

The 907 oil pump has to suck the oil quite high to pump it, so it needs every help it can get in retaining prime. A good oil filter with a proper anti-drainback valve will help considerably. Don't buy the cheapest filter you can find, buy the good one. Just a few bucks more, and helluva lot cheaper than an engine rebuild.
