Pilot flame models
When you turn knob to pilot position and light it you are bypassing safety device when pushing/holding knob down.
Pilot flame gets thermocouple hot which then sends a millivolt signal that energizes/holds magnet open allowing gas flow to pilot flame.
Your pilot flame is staying lit so thermocouple is functioning, magnet is being energized and MAIN Gas should flow
(Magnet is safety device......not energized/held open no pilot/no main gas)
No main gas..
Then remove main orifice and clean it by soaking in alcohol then blowing it out with air (no poking things thru hole)
Clean burner tube.......small bottle brush thru it or push cotton ball/piece of cloth thru it----air blowing will NOT get rid of spider webs which can completely disrupt gas flow
IF still having main flame issues...........gas control (valve defective)
Provided you have correct LP Pressure (11" WC with at least 50% of propane appliances in service---otherwise weak regulator)
