I just disassembled my mr. Big buddy a d it really not that bad. I was able to remove all of the lines a d valve’s a d lean them. I also removed the heater block as and cleaned them also. After all the cleaning and reassemby was complete I had to see if what I did it would still work. Sure enough the ignitor started the pilot and I turned on the gas. All three settings work like new. The issue I was having was the second burner had a big flame coming out of it. It would not glow red like the other one and the pilot would take for ever to light. I hope it will continue to work a d will probably do this every year before putting it away.
