Have now fitted the carbs on the car, changed the fuel line, changed the fuel filter, cleaned the fuel tank etc as described earlier.
We cranked the engine, but the car did not start (cleaned the plugs etc-usual cheks)-i am told because the car has been lying shut for so long-almost 9 months while waiting for the carbs to get fixed-that we suspect the compression has dropped again.
Have put some oil into the cylinders and are waiting for a few days and will try again.
Hi A.D.,
I doubt low compression has a lot to why the car does not start unless you have a hole in a piston! It started once before, so it should start again. It's either fuel or spark. Did you look down the carbs to see if fuel is squirting from the accellerator pumps as you moved the throttle rod? Starting a cold Ferrari engine take a lot of fuel. I often pump the accellerator pedal 3-4 times once the fuel bowls are primed before cranking.
If you've eliminated fuel as the problem, pull a spark plug wire, expose the metal end, hold the end a cm away from a ground source (somewhere away from any spilt fuel!), and crank the engine. You should see a spark.
Also make sure you have a strong battery. Sometimes the cranking of the starter drains the ignition system so much that there is not enough for the spark plugs.
Good luck, and I can't wait to hear you started the old girl up again!
