OBG..
change jets??..the old MSR seemed to run on gas and kero
without changing anything..it came with another jet but i
thought that was a spare...i'll have to dig out the instruction sheet thats around "somewhere"..jet change on the
whisperlite???..it looks like the problem there was that
i was sold the wrong model...

this is the GK on kero..no jet changeing..the yellow
flame got more blue as the stove ran and heated up..
