[Healeys] Fuel Mixture

[Alan Seigrist]

I find the  settings as instructed by the manual to be a hair rich and
often will spend a lot of time on mixture.  Usually I set it per
manual then back off mixture about a quarter turn and I get a leaner
cleaner burn without any loss in power.

Also, hotter plugs can help.
