Retuning from the scrap yard again with a new toy - a distributor from a SE5a that externally looked realy grubby.

On inspection however it had cam lobes that had clearly seen little wear and a shaft that had no play that I could see.

A strip down was a journey that I like to take with pictures to aid reassembley

Some parafin and a stiff brush took a lot of grime away

Especially in here, where some serious muck had accumulated.

The ultrasonic bath helped too - and the sand blaster on the vaccuum unit.

Been caught by this one before - the conncetion between the sliding plate and the earth of the engine is a critical but nebulous thing.

Supplement it with an extra flexible piece of wire like this.
