1950 Styleline Special, 216, 3-spd., all stock.
NEW: Battery & cables, PERTRONIX, wires, plugs, cap, rotor, coil, fuel filter, carb rebuild. Cranks but no start. Seems to be a 'no spark' problem, though not tested yet with multimeter. Could it be a faulty solenoid or voltage regulator? Suspect problem may be in starter button/ignition switch or wiring. Thanks for your help!

1950 Styleline Special, 216, 3-On-Tree, stock. 1955 Bel Air, stock V8.

If it cranks, the solenoid is doing its job.
Likewise, regulator will not prevent starting.
A few questions arise,
Did the present combo of part ever run?
Is the cranking speed as usual?
Have you tried cold start fluid?
Are you sure you have spark?

We just had this in the 1958-1960 forum. I suggested that the ignition module was bad. After that was replaced, it fired right up.

That's the big variable that I see with your situation. The electronic module.

People fear change because it threatens what they know, or what they claim to know.

Will try a new PERTRONIX, and a spare coil.
And maybe get friend Dave here, who knows how to use a multimeter!
Thanks for your help.

If I remember correctly, those used a foot pedal to actuate the starter solenoid, NOT a key position in the ignition switch.

First thing I'd look at is if there is voltage at both key in run, and when the starter is engaged. simple voltmeter from coil + to engine ground should show results. A simple jumper wire from battery positive to coil + would also show if there is no starter bolts to the coil.

Go on from there.

Both of my 50 Chevys had the key switch for on and off but had a push button on the left side of the dash for starting.

Have 4.7 volts at coil. Carb 'popped' when I cranked it after starting fluid spritz, but still no start. PERTRONIX instruction says installation can move timing by as much as 10 degrees, so I should check that next. How do I do that? (distributor has not been moved.) Thanks.

4.7V at the coil seems very low... Did you jumper straight to the battery?

Popping at the carburetor always reminds me of a timing issue. Is this thing wired correctly at each plug?
