In my 28' Chris Craft Sportfisher (Circa 1972) I have this pressurized
alcohol stove. I have to pump it and do so frequently but it never
seems to give me more pressure. Even though I find that there is
plenty of pressure in the 'tank' it won't give me more flame when I
turn the stove up.

I do not have an owners manual on this thing. I see there is an option
on the dial for 'cleaning' what is this about? I have never used any
type of pressurized stove before. I'm considering just getting another
stove and pitching this one. Parts appear to be impossible to find.

Any links or suggestions?
