So I pull the dizzy out, whizz the oil pump over with a long slotted driver in a drill (and it gets good oil pressure fast then) then put the dizzy back on. Getting pretty quick at the whole process without losing time. You just have to line the oil pump slot up to where the dizzy will be when it's in time - which takes a bit of trial and error as the helical teeth rotate it a bit as you push it in.
Your problem may be caused by air in the pipe from the engine up to the gauge . You might try bleeding the pipe , unscrew the connection at the gauge , do not remove the pipe but leave it on the gauge. Run the engine til oil appears at the gauge end , then tighten up the connection .

During the time the engine is just sitting in your shed, oil may flow back down the pipe if a air leak is present at the gauge end .
