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.

<div>History first. I needed to change the jets in my carbs
due to springing a leak in the pipe. Since then I
apparently had some dirt in my fuel so I needed to change
my fuel filter and clean the float bowls that seems to be
OK now . I think I am running rich but I am not sure. Any
help with figuring that out  would be appreciated. Biggest
problem now is that I am having trouble starting if the
car hasn't been run for a while. Never had any problems
with starting prior to the leak. Nothing else has been
changed other than what I described. Any thoughts would be
greatly appreciated. </div>
