Dometic RM2551 fridge won't operate on propane

I looked at the pinhole orifice and could not see through. So, took a very small pin and widened a bit. Made all the difference in the world! I now have a flame that looks like the one Old Biscuit posted.

May have done a little too good a job because I had to reduce the amount of gas going through as it was a bit too good.

Now, the bottom of the flue is hot and the top is not!! Just like it's supposed to be.

Fingers crossed, we may have the issue resolved!
