My Mr Buddy heater worked fine until a friend knocked it over inside my ice fishing shelter. When I turn the valve to pilot and push down it seems there is too much propane being released, and if you push the ignition button down.....the result is a large flame

I had the same problem I called tech support and they said to turn the valve on the 20# cylinder on very slowly for the first 1/4 turn then all will be fine. There is an excessive flow check valve that causes restricted flow when the valve is opened quickly----------mine works fine now
dirt , foriegn material,spider web in gas feed line to the right side ceramic element of mr heater big buddy. take plastic back of heater off, many #1 philips or smaller screws. find large air induction holes in gas feed line to right side ceramic element and blow out with compressed air and fine tiped /straw tipped air blow gun. straw tipped air blow gun is a better tool for this. reassemble & try lit mr heater again. If it dont work after air blow gun the gas feed tube, you didnt get the gas feed tube cleaned out ,***** & span (something still in there ) and will need to disassemble the gas feed tube and inspect for foreign material blocking the gas flow.
If this dont work,need to take the gas feed line off the gas valve attached to Mr. heater red knob. red knob just pulls straight out, might need pliers to grab red knob. check gas valve output for dirt etc that stop gas from getting through. check inside the gas line to the ceramic burner for dirt, foriegn material- that stop gas from flowing through strong.
any stopage of gas flow , even a slight stopage or dirverting of the gas flow, spider web is common, will stop ceramic element from burning properly.
Unfortunately, Mr. Heater does a very poor job of writing user manuals, I didn’t even know my unit had a quick connect until I saw it on the side of the box. As it turns out, the spring loaded fuel **** has three positions; full up for safety lock, fully depressed to select/ignite the pilot, and half depressed to select the heat levels. I guess it was just dumb luck that I managed to get it to work the first time since there is nothing in the manual about this. Since I discovered the third position (sheerly by accident) I have not had any more problems.
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.
