popping through the carb or back fire, how can a lone driver tell what is what? Options

[VaccaRabite]

So, I got to go on a good 15 mile test drive today.

I am starting to second guess some of my assumtions on tuning. I don't know if the car is popping though the carbs or back firing out the tail pipe.

Driving around in 2nd and 3rd gears with RPMs between 3k and 3500, if I lift off I get little pops. If the RPMs go under 3K and I lift, I occasionally got a BANG that sounded to me like a back fire out the tail pipe.

I am not sure if the little pops are coming out the tail or through the carbs. I thought they were coming through the carbs, but I am second guessing myself now.

I did not damage my air filters, so I don't think that the bangs were out the carbs. But I don't know, for sure.

What I do know is that I have more tuning to do before the car is really streetable, and I am not sure what I am hearing, which is frusterating.

As far as drivability goes, the car was great. No hesitation at all up though 5K. I never really got to drive 4th or 5th, its all backroads with blind curves. Power curve seemed flat all the way up.

Only errors were caused by me. I must have forgotten to tighten the lock nuts on the pass side linkage, as I suddenly found myself at 4K idle. and one side an inch off the stops. Fixed the linkage and tightened down the screws, and that was fixed.

When I got home I realized that I had driven the last 5 miles back home with the parking brake on. (IMG:style_emoticons/default/slap.gif) I might have been a bit nervous when I made my road side repair.
