My 66 is Backfiring. When the car has been sitting all day and then i try to start it. It starts funny like shaky. Then when I start going and accelerate it like wants to turn off but it wont. It start doing little backfires then it will do a real one. But then when i get on the freeway and its running for like 10 to 15 minutes its ok. It wont do it anymore. till it sits for a long period of time.
WHAT COULD COUSE THIS PROBLEM?
I checked the carb for leaks and dont have any. I only changed the oil two weeks ago.

Sounds like timing to me.. check your distributor and make sure its where its supposed to be.

If timing is good, check for manifold and exhaust leaks.
