Hi

I have a little BAT stove , made in East Germany (GDR) I think . 

The pump tube is blocked , and the main tube that feeds the burner is blocked. Is this a common problem with these stoves ?

I may have to unsolder the pump tube and replace the NRV ?

While you can unsolder the pump tube, I wouldn't recommend it unless absolutely necessary, or unless you screw up and have to as I did once.  The pip is probably frozen in place, preventing the pump from working.  Since you can't build pressure, how did you determine that the burner was blocked?

You can buy a kit from folks in the UK will will have tools, replacement jet, a new NRV setup and  pump cup.  At least one seller is on ebay with these kits.  If you buy one of these, the NRV tool can be a weak link.  If that NRV doesn't want to easily come out, I suggest getting a specific NRV tool.  I stripped mine in place and that's when the pump tube came out.

You might want to add your first name in your control panel or a signature so we can address you by that.

Hi Jim

Name is Mike .

I removed the burner and tried to blow into the main burner tube ( where the burner threads into ) and it seems to be blocked. I might try inserting wire down the tube .

I will fiddle the blocked NRV and see how it goes Thanks.

Mike. You can unscrew the NRV from the bottom of the pump tube with the right tool .
Bit of wire down the main tube to clear blockage .

Mike,

I don't think that's a good test.  I would think that the orifice being so small, you would never notice air coming out.  Unless perhaps you had it underwater while blowing through the burner, but even then, I don't think that's a guarantee.

I picked up one of these kits a couple of years ago for an Optimus with a Radius burner.  Being a silent burner, you can easily remove the jet by going through the opening under the cap.  You'll use the tool on the left when you get a stove with the roarer burner.

The NRV tool in this  kit is the weak link and was what stripped my NRV.  With the pump tube removed, I replaced the NRV from the back side of the tube (I couldn't get the NRV off the pump tube without risking damage as it was set so tight).

Thanks for the link but it is OK , it's all freed up now.

I poked a thin wire down into the pump tube , I could see a little brass washer and a small hole in the bottom of the tube . Somehow, after poking around , it freed up. The NRV is working OK now.  The other blockage was on my stupid brain ! The main tube is also OK .

I need to buy some kero, the only supplier around here these days is at the hardware, it is Diggers brand ( blue coloured ) . There used to be a bulk fuel depot in town, you could take a 20 litre jerry can to the depot and they would fill it up with kero for 10 bucks, those days are gone sadly.  Mike

Go Mike. Go to read you have it cleared.

If you are just test firing it you could get old school paint thinner as fuel. Do NOT get the newer stuff. Our hardware store sells both. I even add 10% Coleman fuel to this mix. Fires up faster IMO.
