Weak oven pilot - was trouble with Magic Chef '79

[blickcd]

I took a good look at my oven pilot light this weekend. Removed the oven bottom or steel plate just above the burner for complete access and blew everything out with compressed air, despite nothing looking obviously wrong.

I then lit the oven and top pilots. The LP regulator is only a few years old and so I don't think it is gas pressure related. Starting from cold, the oven pilot burns, but not really strong. Because of this, when you turn on the oven the rush of gas out the burner actually blows out the pilot.

If I manually light the oven burner and get the pilot light going again, after the oven runs just a short time and is shut off, the oven pilot burns nice and strong. At this point the oven would be good to go turning it on and working properly.

In short, lighting the pilot from a cold start, the oven is likely not to fire up on the first try, but once operated would be good to go until the pilots were shut off. Any ideas as to what the probelm is?
