Optimus Campingo 1 - jet cleaning tools

Hi,
I'm a new to this wonderful forum and have just started to refurbish an old stove that I think, thanks to this forum, managed to categorise as a Optimus Campingo No:1.

It is in quite a bad state, but it looks like I can get pressure in the fuel tank (Changed the pump leather). Unfortunately I made a mistake and fed it with lamp oil instead of kerosene. Now it doesn't seem like any fuel comes out of the jet and when increasing the pressure by pumping the valve is leaking. I'm suspecting that the jet needs cleaning and/or replacing.

My questions are now:
1. Which tool should I buy to remove the jet (Didn't find any tools in the box)? Is it a 207 burner?
2. What tools to use for cleaning the jet?
3. Could there be another problem with the valve that is stopping the fuel from reaching the jet? I disassembled the valve and it looks OK to me, including the lead gasket.

I will try to post pictures soon.

 

Photos would help; especially the burner so we can recommend the best tool.

Here are some pictures. I wonder if it might be the case that this stove has been modernized with a silent burner, or was that already available in the 1930s?

 

BD had a silent Campingo 2.
They obviously do exist.

 

What an excellent find!

You should be able to get the correct tool from Fogas.se; they are excellent to deal with. If you’re unsure of the catalogue, send them an email with a photo of the burner.

Thanks!

Good idea to send the picture to fogas.se.
Got my pump-leather from there but didn't know which tool I should order.

It was interesting to see that the stove is really quite old. I found it in an old abandoned cottage in the stockholm archipelago. I'm kind of wondering if I should try to fix it or maybe pass it along. There is great joy in getting these things to work, but I also don't want to destroy a possible collectors item.
I already own a working Optimus no.5 and a mint condition ex military Hiker 111 and too many gas camping stoves.

 

It is certainly a collector’s item.

Thanks for the help!
This project has been lying still for awhile, but since I recently found a few old kerosene pressure lamps I wanted to get in working order I decided to order some spare parts from fogas.se and indeed they had the correct tool. I removed the fuel nozzle and cleaned it with a modern pricker for a multi-fuel stove I have. It indeed seemed clogged.

I then managed to get it to burn albeit with a bit of a yellow flame and the valve started to leak after a short while burning. I wonder if the lead gasket on the spindle does need changing too, or maybe it just needs more cleaning?

 

Can first try tightening the jam nut first, just a little at a time, as long as the valve still turns without being too stiff.

Thanks,
I did try to tighten the nut quite a bit, but my impression was that the valve still turned very easily. Can you see anything suspicious on the spindle? Could the tip be too worn as well maybe?

 

The stove is now running fine!
I changed the graphite gasket around the spindle, tightened the nut and got rid of the leak.
I had some strange yellow flame on one side. I tried to align the burner more horisontally and cleaned the jet one extra time. That seemed to take care of it.

 

Something that intrigues me with this stove is that it doesnt seem made for the silent burner. It protrudes over the grille. At the bottom of the on the sides there are two loose angled iron bars. I wonder if these are for adapting the height of the pot over the burner. They don't seem quite the correct size though, but that could be because the tin box is a bit warped.

 

Here is another picture of the protruding burner and the bars.

 

The valve shaft knob looks like for a early Optimus stove. The silent burner not likely made for this stove. Two strikes.
