[Healeys] Mechanic/Starting Problems

[Bob Spidell]

Edward,

One minor technicality, re: "When the choke is pulled this brass rod 
should slide up and down and move the throttle just slightly,enriching 
the mixture."

Opening the throttle does not enrich the mixture.  On a properly setup 
choke for HD8 carburettors, about the first half of the choke travel 
does open the throttle--for a faster idle--but the second half, whilst 
continuing to open the throttles also lowers the jet, which does enrich 
the mixture.
