I discussed my engine problems with the chaps at work. One contacted his brother in law who suggested it was a leak between the carburettors and the inlet port.
I had a look at all the connections and they looked fine and tight. So it could be the vacuum advance or the engine breather. A finger over the vacuum advance port had no effect so the breather was removed and a 3/8” socket extension stuffed in the hole.
Eureka – the engine runs at a constant speed - very fast but the idle speed was adjusted quickly and Jemima was left to idle and warm up for the first time in 20 years.
The garage filled with smoke from the oil that was burning of the outside of the engine, the exhaust was emitting less smoke now. Actually I’m using leadfree with a slight diesel contamination due to a mistake at the pumps several months ago so a bit of smoke is expected.
The BMW thermostat finally switched on at 99˚C but it was connected to the slow side of the fan so it didn’t have a great effect at first. The lower temp switch doesn’t seem to be working. I switched Jemima off and allowed her to cool down.
Next day I came back to start her up again and all I got was a click from the solenoid again. Out with the starter motor and a recrimp of the stud-winding connection got her restarted again. I’ll change the motor next time.
