1 or 2 burner washer/packings

I could not resist this nice Primus no. 5 on swedish auction-site Tradera. For app. the same price as a bag of groceries I got this nice silent burning 2 pint stove.



I cleaned the tank with some clean kerosene. Not surprisingly the stove needed a new pump leather and the spring in the nrv was disintegrated. I also changed the burner head washer/fireproof packing above he spirit cup.



When I made my first cup of coffee on this seemingly unused stove there was a bit of smoke/kerosene fume coming frome underneath the spirit cup. Should I put a burnerhead washer underneath the spiritcup as well?

 

Yes. I got two identical washers in the kit a recently bought for a stove.

 

Most if not all I have replaced use two. Also learned to only tighten the burner hand tight.

@Outdoorsdad and @hikerduane thankyou.

After taking off the burner head and the spirit cup it was easy to see the sorry remains of a washer. I quickly scraped of the remains of a washer:





And after i stalling another washer all is fine:




Next time I will keep in mind not tightening it too much. But for now it seems fine.

by the way, can someone explain why coffee made on a brass stove taste so much better?

 

The washer material shrinks fractionally after first firing and a seal is restored by tightening the burner.

 

A mug of tea tastes even nicer nice stove and flame

 

I hate the dreaded wisp of smoke after fettling a stove, even worse on a 96 is seeing kero run down the fount.
