Blackstone Pizza Oven Issue. *Not Regulator or Tank

Nothing like asking a Blackstone question on a ceramic grill forum but I know a bunch of you have these and know more than I do about them!

I'm having an issue with a used Blackstone pizza oven I picked up. I can only get the Blackstone pizza oven to heat up around 325 degrees. I can hear and see the Blackstone isn't getting enough gas or pressure to increase the heat/flame. Here is the head scratcher....it's not the regulator or the tank.

I swapped over the regulator and the tank to my other Blackstone pizza oven and I'm getting full pressure with no issues. You can hear the pressure difference between the two ovens.

It has to be something within the Blackstone pizza oven as I've eliminated it being the regulator or tank. I've done the whole Blackstone recommendation of disconnecting the tank, opening the gas line and releasing gas in the Blackstone line, waiting 15 minutes to reconnect the tank, and slowly opening the valve on the tank. I've done this multiple times. So I'm confident it's not tripping anything as I have no issue using the same regulator and tank on my other Blackstone.

What is going on in the black metal pipe the regulator gets threaded onto? Is there something in the pipe that could be causing the restriction? I can't see how that pipe could get bent causing a restriction flow. I'm tempted to blow it out with compressed air but I didn't want to jump the gun where I could ruin something as I don't know what going on in the metal line.

I'm just looking for some suggestions or wondering if anyone else has had a similar problem. I appreciate any help!

    Did you look here? You can find the schematics in the owner's manual

    The troubleshooting chapter looks promising.

    if its not the tank or regulator next up would be all the gas flow areas for bugs and debris.  ive seen those mud dauber bees seriously clog lines

    Sounds like it may be a clogged orifice.

    Take the line off and back blow through the burner using compressed air possibly. Maybe some corrosion flaked off in the pipe. If there is an adjustable air intake on the burner maybe some dirt daubers got in there.

    fantastic!. I had that problem with mine and didn’t notice it until I compared it to my neighbors. Switching the regulator fixed mine. Now I need to find a perfect fit stone since I dropped mine and cracked it. Long live the Blackstone!

    Please keep me updated on what you find for a replacement. My other Blackstone stone cracked from use and I've looked in the past but it's an oddball size and finding the right size thickness was tricky. I think I found one at one point and saved the link but it has been a minute.

    @GlennM

    I just asked over on the Blackstone Pizza Oven forum and now it's all coming back to me with the answers I received. 

    When I purchase a replacement stone I'm going to go with a higher temp Cordierite stone. The Blackstone measures 16.25". So I'll be losing a quarter in of stone but I feel it's worth the trade off in temperature. One of the guys on the forum said he bought a Cordierite stone for his pizza business and has cooked thousand's of pizzas on it the last four years and has never had a problem. My Blackstone stone must have cracked due to the heat as I've never dropped it or washed it in anyway. 

    Another person on the forum mentioned you can still buy a Blackstone stone through Blackstone if you wanted 16.25" OEM. It's not listed on their website but maybe worth emailing if that is the direction you want to go. Otherwise there is a link for the 16" Cordierite below:
