Torpedo heater

[mystang89]

Hey everyone. I was given a few torpedo heaters which didn't work and I figured I'd try to fix them. It seems 3 of the 4 turn on just fine but no flame comes out. I took the top off and looked at it while the unit was running and there isn't any fuel being sprayed through the spark.
I cleaned the spark plug. Took apart and cleaned the fuel nozzle. Replaced cracked hoses. Took a photocell from another torpedo that I knew worked and put it on but still have the same problem. It has fuel. Any other thoughts?

Are the pumps airbound? They're supposed to be self priming but sometimes when they're older and the seals are dry it can take a while to get them primed

How do I check? Dip them in some diesel?

Make/model may help.
Mine has an air pump and uses Lp air to feed fuel. 2nd on finding a trouble shooting guide on the web/utube. I was pretty surprised how simple they are when I had to resurrect my '80s era model after years of minimal use and a flood.

2 are reddy heater r200
One is a reddy heater r150
One is a Dynapro rmc-kfa210tdgp-02
I've watched about 4 tutorials on these heaters so far from YouTube but haven't found the problem yet. What I've fixed on these heaters was because the tutorials were saying they might be the cause

Set the air pressure first. If that’s not right, they won’t work.

Ive got one ive had for years. Little like 3/4 inch hole in the back. Wont start. Shove w wad of paper towel in that hole it works great.

I know its a hack. But in AZ I don’t use it enough to care!
