Natural gas to propane range

[gear jammer]

In the cabin I was trying to clean the range. It was bad. Found a used range set for natural gas, clean and priced nicely. Trashing the old one and bought LP orifices off GE site. I put the orifices in and put the bake orifice in. No broiler or center burner. I cannot get away from a yellow flame. Even had the tank refilled. Suggestions?
Thanks.

The range may have a regulater set for NG. That would cause it.

We recently bought a new gas range. It came set up for Nat Gas. It had LP burner orifices but also had to change the on board regulator by taking the cover off and flipping a part over. You Tube might help
