LOL Ross

Speaking of transparent, next problem:

Clogged? It's the pilot jet for the catalytic heater.... Everything eventually clogs... first the 2 torches last year, now this...

I have good flow thru the pilot line itself, and I can draw a respectable flame from the pilot side of this without it being in the carb...

That little window is transparent something or another, but what, and what can I clean it with?

The pilot is crucial to the safe operation of the heater.. I need to resolve this asap, please help!

Blowing it out helped a little, but the pilot still isn't what I'd call "good"... enough to run the night, I hope. It's of course failsafe, but it was quite a surprise when I opened up to come out from the house.

What the hell causes this? I even got a fuel filter to put inline because of the BS with the torches last year, but apparently whatever is doing this is getting thru it.

The damage to the face was already there when I took it apart, I know I didn't do that, as after I broke it free, I unscrewed it the rest of the way by hand. It apparently isn't the issue because it has been running ~ ok and was perfectly fine a couple years ago when I last used it (way too powerful for the van).

The still doesn't capture it... it's feeble and flickers quite a bit.. it used to have a torch-like appearance and rather stable once upon a time...

it is a glass orifice jet. spray some carb cleaner through it in the opposite direction of normal flow

Cool, much appreciated... when it fouls again I'll give it a shot.

I noticed the inside of the tube for the jet was more or less coated with soot... why would that be, there's no combustion in there...? Or is it something else?

just dirty propane, you will usually see a soot like substance inside most well used propane fittings. it is worse in a jet because of the flow to surface area ratio.

I think I've mentioned it somewhere before, but I should write a book, mmmm?

(All stupidity aside, those batteries in the foreground are so beyond dead it's not even funny... looks like concrete inside and the voltage across the terminals is something like a whopping 0.3V or so, give or take)
