New engine, little to no spark!
The 302 is ready to fire-up for the first time. EVERY part from oil pan to carb is new. It has original style plugs,wires,cap,rotor,points distributor,and coil. All the parts came from HeartBeatCity. The problem is seemingly very weak spark at the plugs. Once in a while you get a nice blue spark while cranking, but mostly it's very small or not at all. This what I've checked so far;
* Brand new fully charged battery
* 7 volts to coil in "run"
*11 volts to coil during "crank"
*Timing set at 6* BTDC
*Points gap set at 19 thou
I tried the new coil on my truck and it started my truck fine, but my truck gets constant 12V to the coil. So, I put the coil back in the car and ran a 12V jumper wire from the battery, still no good. If I put a spark plug directly into the coil wire, I get decent spark! I'm not sure if it could be a bad condensor in the distributor that could cause this, so I've ordered a Pertronix module to replace the points and condenser.
I just want to spend extra money when it could be something simple that I have missed.
