Post Ignition Circuit

Fially ! .

My worthless long out of date Chevy training comes in use full ! =8-) .

Because this vehicle has a manually operated pedal starter there is NO SOLENOID & BY - PASS CIRCUIT ! .

One you've ascertained voltage at the coil, disconnect both wires and test the resistance across the two smaller terminals ~ if there's a ballast resistor on the firewall you use a 1.6 Ohm coil .

If you wisely delete the ballast resistor you use a 3 Ohm coil .

I highly suggest an epoxy filled coil, they're cheap @ NAPA , avoid the Pep Boys, Autozone & O'rielly's Chinese ones .

The gap is .016" or 25 degrees i9f you have a dwell meter .

Once it's running, set the initial timing advance at 800 or less RPM's and make sure there's NO VACUUM SIGNAL to the dizzy until you open the throttle

I ASS-U-ME'D this is a V8 ? .

If it's a 6 cylinder the dwell is 33 degrees and the timing marks are on the flywheel, look just above and behind the starter motor, you'll see a little widow with a steel pointer in it, there's a ball bearing pressed into the flywheel and you need to set the ball on the pointer at 600 or less RPM .

Also, if it's an inline 6 Banger, you're going to need to adjust the valves before anything else, guaranteed they're tight and this will cause hard starting and such bad idle you'll have trouble timing it .

I love these old "Task Force" Chevy trucks, please share some pictures even if it's nasty .
