B20 that won't ignite 120-130

posted by  someone claiming to be Fredrik on  Tue May 20 20:42 CST 2003 [RELATED]


I'm having some problems getting my car to start this spring. I've had it tucked away in a barn over the winter. It's a 1969 121 with the B20 A engine and one Zenith-Stromberg 175 CD-2 carburettor. The fuel pump is new, the air filter is new and the carburettor is cleaned. In other words, there is a constant flow of air/gas mixture to the engine. There are nice, blue sparks coming from all four spark plugs and the ignition order is correct: 1-3-4-2 counter-clockwise (actually untouched since it ran perfectly alright when last used in October). But the engine won't ignite. Not even a puff... Even tried tow starting it, but that didn't help either.

I did what I would like to believe was an accurate ignition setting in June last year, using a stroboscope, and the engine ran smooth like a sewing machine for more than 1200 miles after that. If the spark from the spark plugs comes at the wrong moment in time, the engine will not ignite - correct? This is my only lead right now, but before I tamper with ignition settings previously known to be good on a car that won't even start, I'd like to be more certain. Is there a "base setting" of the ignition for which the car will start, so that you afterwards can perform a more precise setting (when the engine is running)? What would such a setting be?

I would greatly appreciate any help, comments, hints and advice here since sitting behind the steering wheel of my Amazon inside a barn simply isn't the same thing...

Thanks in advance,

:: Fredrik
