i think i have a problem with my ignition timing. here's the deal. in order for my 258 to run, and have any kind of throttle response/power, i have the timing set at around 17 deg BTDC. i think this is to advanced. if i set it at the recommended 9 +- 2 degrees the engine will run but not have any power. like i cant get out of my driveway without almost getting broadsided.
here is my testing technique. unplug vacuum advance hose, plug hose with screw. clip timing light on #1 (closest to radiator) spark plug wire. check timing. am i missing something? my timing light has a dial to set degrees advanced and i have to turn it to 17 deg for it to line up with "0" in the timing marks.
i dont have any noticable pinging, and i run 87 gas.
on a whim i checked to see if maybe the harmonic balancer was off kilter, thereby throwing off the timing marks. i pulled the #1 plug and stuck a coat hanger in the hole, and turned the engine with a bar. sure enough, the timing marks do indicate TDC on #1.
i am afraid i am damaging my engine, even though it's not pinging at all. but the thing isn't drivable if i retard the timing any more. is there something i'm missing? please help!
