@halifaxhops Ray, i opened up my distributor, one spring was stretched. And the tiny pin it hooks on was worn almost all the way through. Also the slot on the shaft was worn badly. Pulled my spare and robbed parts to repair it. Thats fiddly work imho.
And it turns out the vac advance on it was good, whomever put the vacuum line on it cross threaded the fitting. Im still going to use the new one, but this gets me closer to a better running engine. Definetly needs all the help it can get. All cleaned and oiled, ready to fire again.
