RPM gauge and trigger query

Ha ha! I'm going to remember that term 'the magic blue smoke'. That car sounds like it was a lot of fun to drive!

I realise now that everything you have said not to do for a sound primary ground connection this aircraft has. From powder coat to washers and regulator housings to half a metre of aircraft subframe everything save the kitchen sink has been installed in the way.

Magic!!!

Thanks once again Bill and also Garrett for the link about the dielectric grease.
