Yup- I fixed a friend's pump with a slightly modified feeler gauge, chosen for the "carefully measured
" flex. Many older units I have seen run a disc shaped reed, which might complicate the fix.
I was very fortunate- my uncle found my compressor for me. A "Westinghouse" 2 horse 220v single phase, dual stage, 80 gallon horizontal manufactured in 1949 by the tag on the tank. It lived it's entire life in a service station run by a very fussy owner with strict rules for his employees. My cousin was one, mid seventies. Draining the tank at the end of shift was NOT optional. You oughta see this motor. Big as a 5 gallon bucket, 100 lbs of AMERICAN horses. The tag says 2 horse. It draws about 27 amps! Runs cool, dead quiet, original bearings. The tank has been drained very religiously since I have owned it, I have run a hammer over the bottom of it more than once, and I trust it completely.
