backfires when i turn key off

Well it may start once or twice, but if your carb is out of whack you will be back to square one before long. If it does fire up then you know the plugs were bad, once you determine that then you can address the reason why it's happening.


Also you said you had the distributor out. Did you get it back in properly? It could be a tooth off if you disturbed the gear which would give you fits. Also make sure your wires are oriented correctly on the cap and going to the proper cylinder.

Keep us posted here, you'll get it.
