The metho is not running to the burners so I have to find the blockage.
I do have fuel and I have tried opening and closing the on/off switch many times.
Any ideas?

are sure its not pressure metho and requires the tank pressurizing with a bike pump not all metho stoves are gravity feed

I have to pump it before I light the burners each time.
I may be able check fuel flow from the method tank just by loosening the connecting line.
May I will try pumping air through the stove lines.

Do those knobs have a push or pull action as well? Is there a warm up ring around the burner?

Yara,
I owe you a beer.
I think I figured it out.
Yes there is a warm up ring around the burners.
I will go to my boat tomorrow and let you know.

I thought for sure I must have a push pull system but no. What disappointment, but I have another idea.
I filled the metro cylinder to the top, but I now understand, the more air I have in the cylinder the better it will flow?
I will syphon two thirds out and have another go.
Any other ideas?

As long as there is some air space in the cylinder, and it is pressurized, you should get some flow. When you have more airspace, the pressure will drop more slowly. Maybe there is gunk in the bottom of the tank. Can you get to the pipework?

I did fill it to overflowing accidentally so it my intention to syphon half off.
If this does not work I think I will be able to disconnect and remove both the tank and the burners.
I like your idea of possible gunk in the bottom of the tank or the line. After 34 years you would expect some.
Thanks for your help. I will let you know how I progress.

FIXED
Thanks Yara for your suggestions.
Firstly I disconnected the fuel line at the pump. Yes the pump was working.
I then tried to blow air through the line to the stove, no luck with that.
I then tried the knobs and they turned and out came the method.
I think the problem was I had pumped so much fuel, there was a high pressure build up at the switches which stopped them from turning.
They turn fine now.
I could be wrong but I have a great result.

NOT QUITE FIXED
After pumping the tank and turning the knob, the metho flows freely to the burner but then dries out and the flame dies.
I have presumed that once lite, the lighted flame would continue to draw metho to the burner.
I think this is known as "capillary action'
Am I wrong?
Do I need to continually pump the metho tank?

Do you have a pressure gauge or a pressure indicator on the stove.?
I run about 75 kPa or around 10 psi in my kero stove.

Yes I do have a pressure gauge/indicator.
I will try keeping the above amount in it.

Pump it up without lighting it and see if it holds pressure for an hour or two. Mine often leaks pressure from the tank filler cap as that is what I use to release the pressure from the tank so the seal in it gets a bit of a constant work out.
Make sure the tank is not too full. I usually find my stove builds pressure as it gets hotter so once I have lit it, I in rarely need to re pump it and sometimes I choose to release some pressure.

Is there a nameplate on the stove? Have you talked to the previous owner about it? Looks like a quality piece of kit, so there might be an instruction manual on the net.

Success at last.
