[Healeys] spark plugs for '67 3000 and flooded engine

[Len and/or Marge Hartnett]

Steven:  A Google search came up with an informative article on spark plugs 
from ntahc:

http://www.ntahc.org/techtips/sparkplug1.html

The final paragraph says:

"...So what do you choose? Well, if you are concours, use the original spark 
plugs. If your car's engine is essentially set up the way that it left the 
factory, use the factory recommended plugs. If you have added power 
improvements to your car (higher compression ratio, more cam, more carbs, 
electronic ignition, multi-spark discharge, more powerful coil), consider 
stepping up to the next colder heat range. Added real power? Move two steps 
colder. Then, read the plugs after 100 miles, 500 miles and 1,000 miles. If 
the plugs are fouling or coated with carbon, move back to the next hotter 
plug. If the ceramic is cracked or chalky or if either of the electrodes is 
burning away (the gap has increased) go colder...".

The factory recommendation is Champion UN12Y.  I have been using them since 
I acquired my Healey (1970) without any problems or known loss of 
performance.

Can't help on flooding other than to recommend that you check to make sure 
you are getting adequate spark at the plugs and not applying too much choke. 
"Experts" will have more recommendations.
