I just picked up a Turner T15C gasoline blowtorh, "new" and unused with instruction manual but a little shelf worn last week. From the appearance, it's probably 30 or more years old.
The leather gasket in the pump is good, the check valve is good, the wick looks fine and the orifice isn't clogged, but something like rust or black powder came out and there appears to be no seal along the valve shaft and the packing nut on the read. One website suggests this can be replaced with grahpited string, like on a steam radiator valve.
I went ahead and fired the thing up with camping gas and it did light but made a weird pulsating sound, a little faster than once a second and the flame never really looked right with a yellow tip.
I also noticed that in the off position, the needle from the needle valve actually stuck out from the orifice itself by about 1/16th of an inch. I suspect this isn't right.
Any tips for dealing with and fixing these things? The stuff on this site really doesn't really dig too deep
Any good stories of using these or advanges to propane torches?
