Here is what I found out.
I took off the burner and the housing that the burner sits in to get clear access to the underside of the perk tube. Talk about tight working conditions. I used my phone to take some video looking up the tube and there is a little rust but not a lot. No debris or anything like that came out. I can reach up inside the perk tube with my finger and touch the baffle. It seems to move around a little but I think its supposed to. Not sure about that. When I touched it, it seems to move up slightly and then settle down into a set position. I put everything back together and turned it on to make sure everything was working. It does light normally but it is a little cool out to give it a fair test.
I don't have a way of testing the gas pressure so when the weather warms up if it still isn't operating properly I may have to take it in to someone that knows more.
We'll see when it warms up.
