LG DLG3601W No Working after LP conversion

Hello, I hope someone can help. I converted a LG gas dryer to LP but now the heat wont stay on. I installed the valve and adjusted the regulator. The flame comes on but then shuts off pretty much right away. The flame seems weak and looks like its hitting the temp sensor. Any help is appreciated…

Techmotivated, if there is a verified LP gas supply going to the dryer, the limiter may need to be backed out 1/16" (or a 1/8 turn) if there is not an air blockage. It sounds like either the gas or the air is being choked off.
