When I took auto mechanics in school, our instructor had all sorts of devious tricks he would use to baffle us when teaching troubleshooting. A worn bushing in a distributor was one of them. He also had vacuum hoses made with orifices hidden in the hose, that would act as a restriction, causing delays in the vacuum signal to/from the distributor and other vacuum operated devices. We always looked twice and always started with the very basics. Use of vacuum gauges and multimeters were "beat" into us.


I have looked for the clearance specs of the two bushings for the distributor on my 59AB, but no luck so far. I know the rule of thumb for Babbitt clearances is .001" per inch of the shaft diameter. For bronze bushings?
