[Healeys] Hard start

[Bob Spidell]

Best way to get a 'quick read' on mixture is to use a ColourTune 'glass' 
spark plug(s). I bought two years ago--for a tri-carb you'd want 
three--and they've paid for themselves over the years (and they keep 
getting more expensive). You can also use the 'piston lifting' method, 
though it's hard to guesstimate a 1/32" lift; the (not so anymore) 
'cheapie' tuning kits--handy for the money--has wire inserts that 
indicate piston lift and the little jet height-setting tool is alone 
worth the price of admission. Or, you can tune 'by ear'--best to 
separate the carbs at the linkages--and confirm by 'reading' the plugs 
and the tailpipes.

My cars--BN2 and BJ8--have always been harder to start the longer 
they've been sitting. Be sure to let the pump fill the carb bowls--and 
make sure it stops--before cranking. It helps some to press the petrol 
pedal to the floor before you pull the choke cable all the way out. 
Double-check your choke mechanisms and settings.
