Quiz Time: Nord no start x 2

Ok boys and girls, it's quiz time: Why wouldn't two seemingly different cars refuse to start.

Case one: 1962 Giulia Sprint 1600. Single Solex carb. In dry storage for a couple of years. Owner routinely started the car maybe every month or so. Never a problem other than a dying battery. We repainted it, did nothing to the motor. Went to deliver it to the client after a few months - no start.

Case two: 1979 Sprint Veloce. 2 liter Spica project car. After several years in storage the motor was recommissioned by the PO with lots of new stuff including electronic ignition. Ran crappy when I got it but after a SPICA set up the motor ran well - for a while. It suddenly died and would not fire.

Both motors had the big three: spark, fuel, compression.
Properly timed (cams and ignition). New plugs, plug wires, battery, swapped in know good dizzy. Sprayed with starter fluid.

Crank, crank, crank... Not a single pop.

Once I realized what the problem was they both fired up and ran like new.

What was the problem?

Prizes: Something perhaps that you are missing on your Alfa that I might have in my inventory (within reason - if it's too valuable I'll lie and say I don't have it...).

Or a set of SPICA new rubber fuel grommets.

Hints forthcoming...

Ok, I'll bite. There's spark, fuel and compression but no air. The air cleaner elements are either completely fouled with something (dust??) or the intake runner was masked during painting and remains so...

If there is compression, there had to be air, and the starter connecting to the flywheel for cranking.

Since both cars ran before, one can assume the timing was correct and didn't change.

Waiting to see what mysterious gremlin caused the no-start. It has to be so basic that we aren't thinking of what it is...maybe something wrong with spark plugs on both cars?

Spark is there but at the wrong time. Plug wires mixed up?

My guess is fuel delivery, possibly from debris in the gas-tank clogging the lines. Happens all the time with old cars. No gas, no start.

We have a winner!! In both cases the fuel in the tank had turned to varnish. Good for old wooden boats, not so good for old Alfas!



I certainly should know better to clean out the tank before I try to start a car that's been sitting for years. But...

Ok Exhausted, PM with something you need for your 105 and I'll see if I have it.

@Jim G , if you need any of this for refinishing your wooden boats, you are welcome to it - it's not great for running cars...
