Hi! Lucien
Just to explore the topic further ...whilst I would never advocate not
changing the crush washer.... if it is a solid copper ring and you have
forgotten to have a replacement on hand then it would be best to refit
it after you have annealed it .....heated it cherry red and quenching it
in oil.(the opposite to hardening steel!) That will restore it's
flexibility to reuse. However many crush washers are made of light gauge
copper and are rolled and so folded to allow the crush to take place
(like on ignition plugs) these would not be suitable for annealing. I
have a 1936 Velocette OHC 350cc motor cycle and it's head gasket is a
solid copper ring about 3" diameter which I have never renewed but
always annealed without ever leaking

My .02,
If I have a crush washer on me when I do my oil change, I replace it.
I'll reuse old ones, tho. Copper will harden a bit once it's crushed so
a used washer isn't as pliable as it was (besides already being flat as
a pancake).
But at the specified torque (195 in/lbs I believe?, can't remember off
top of my head), the drain plug usually still gets a good seal and
doesn't leak.
And yes, I wouldn't even consider not safety-wiring the drain plug after
installation new crush washer or no....... yeah it's extremely unlikely
a properly torqued plug could come out but the wire reduces that
probability to as close to zero as you can reasonably get for just a
little bit of effort ;)

Thanks for the tips Ron and LS. I will check the ground wires.We don't have
alcohol in the fuel here yet.(not for another two years) I am pulling the plugs
today and will check them for carbon.I always use the silicone compound on
the plugs and torque to the book.
Hopefully the premium auto gas will do the trick ,if not then on to a mix of
avgas.I have just started using the new Aeroshell Plus 4 oil and it will
handle either fuel. It's a 10w40 oil but pours like water.

Hi Dick
I just remembered hearing from Lockwoods years ago that if you get the
ignition modules hot you can not turn motor off. I wonder if one of your
ignitions give you a spark or 2 out of phase on shut down??
