The mr heater series units have a millivolt generator connected to a very small sensitive electromagnet in the valve body. inside the generator is a small insulated wire connected to the very tip of the generator. that and the outside copper tube forms the j-k junction. at the other end, the part that goes into the valve is a silver button and a gland nut. this forms the other part of the electric circuit. the inside of the valve has a spring and an iron slug with a rubber pad. the slug gets sucked into the electromagnet when the magnet is operating and holds the pad off its seat allowing propane to go through the regulator and valve. change out your generator and I'm sure your problems will be solved. mr heater has a web site.

No propane comes thourgh pilot on mr buddy heater

If the pilot will not light get a q-tip and alcohol and remove the wire grill and be sure the cotton doesn't come off the end of the stick wet the cotton with the alcohol and twist it and push it down into the pilot tube 2 full inches. Let the alcohol soak for 30 seconds and while twisting pull the q-tip out. Try this until the pilot lights.

ok, your unit must be propane. look on the back where the propane line feeds the nozzle. there should be a very small copper line with two spade connectors on it. this is your millivolt generator line. with a flame at the nozzle the generator makes a very small electrical current which feeds to the main valve and keeps it open. take a piece of wire and jumper these two spade connections together and try lighting the unit again. if it stays on, the hi limit is shot. you can get by with the connections jumped out, you just don't have the safety margin if it were connected. IF with the spade connections jumped out the unit still shuts off, the generator tube needs to be changed.
