Dometic RM2551 fridge won't operate on propane

If it was me, I'd buy another orifice (I've been repairing furnaces since 1970). The hole size of that piece is critical. There must have been something partially blocking it. Wallowing out with a pin as you did could cause problems later. May as well benefit from an undamaged one while you own it. You wouldn't want to pass it on to a future owner in that condition (liability).
