About 2 months ago, a member had a brilliant synopsis to simplify the
gasoline engine:
"It's about Air, spark and Fuel....in the right amounts, in the right place,
at the right time"
I thought this was great as it focuses your attention went fault finding.
So, using this simple approach:
1. You have spark but, is your timing correct? (Check that dizzy rotor
points to #1 spark lead just prior to TDC)
2. Your fuel bowls are full but, do you have vacuum to ensure that fuel
is being sucked through the main jets? (Check for obvious leaks such as
your brake servo hose either at the servo or at the manifold).
3. What is the quality of your fuel like? Did you use fuel stabilizer
when you stored the car?....petrol can turn to resin if left too long.this
can plug the arteries of a carburetor...usually a bigger problem with fixed
choke carbs like Webers than with SU's.
4. Is your fuel pump working? Are the fuel bowls pressurized?
Good luck
Regards,
Paul

Subject: [Healeys] BJ8 doesn't want to start
I am having a problem getting my BJ8 to start. It has been sitting for a few
months while I replaced the starter with a gear reduction type starter and
did some work on the cooling system.
The car will crank, there is spark at the plugs, and there is fuel in the
carburetor bowls. I sprayed starting fluid into the rear carb with the aid
of a short section of hose and it tried to run but I could not get it to
start after spraying more starter fluid. My theory was that if the engine
ran for however long with starter fluid it meant that there is a problem
with the carburetors. What part of the carburetor could be causing the no
start condition? Fuel is getting to the fuel bowls, the fuel bowls are full,
I checked that the Gross Jet float valve were not stuck. What am I missing
in this diagnostic process?
Thanks
