I installed rebuilt heads on my 72 Malibu. The only things replaced were the heads and the thermostat. I have spark at the plugs but the engine will not fire but it does backfire through the carb. More so depending upon where I rotate the distributor. Everything is hooked up can someone give me some help? I am pretty sure I did not stab the distributor 180 degrees out. Any other ideas? Thanks. :confused: graemlins/angry.gif

I've been pretty sure I didn't stab the distributor 180 degrees out a couple of times and I was wrong redface.gif

I'd do the old finger over #1 spark plug hole trick to recheck it.

Thanks for the tip. I checked once again and much to my suprise I was 180 out. Thanks again.
