Optimus stove NRV.

[Swifty]

Heres one for any ageing scouts...

Rumaging in the loft the other day, young swifty found an Optimus primus stove in its original case!
Got the meths and paraffin out the shed and we fired her up... Amazingly it ran first time.
After a few minutes the pressure was obviously leaking away and I noticed fuel was dribbling out the pump.
Anyone ever stripped out the non return valve or got the funny tool to do it?

[Biggles]

Swing the lampshades. But we used to use a similar system on a No2 burner in the army.

It used to be just a case of unscrewing the plunger and replacing the large washer that was on it.

Guess you'll need to find somewhere that has the washers available or has intimate knowledge of Optimus stoves.

As with most things in this day and age might be just as cheap to buy a new one unless your lucky in finding a source of cheap spare parts.

Isn't it just a cupped leather washer?

Sure is a cupped leather washer that has dried out. Take assembly out and soak for a few days and put back. Should work.

The leather washer is ok, there must be a non return valve on the end of the pump chamber, but its an unusual keyway which you can just see at the bottom of the pump tube. Dont want to get it out and find its not what I thought it might be.
