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?
