Weber carb set up help, Jetting seemed to help but still slight popping/backfire Options

[North Coast Jim]

Just finished a new 2 liter engine build with Webcam for carbs installed.
New Raby heads, Hoffman Eng, are used. New 44IDF Webers installed with cross bar linkage. Valve lash to spec and timing is spot on. Carbs are synched. Continue to hear a slight popping from only the pass side carb at partial throttle positions. Car starts and idles with plenty of power thru acceleration, but who knows I haven't driven one in over 25 years. It's a hoot to drive except for the Issue. Played with jetting to no avail. Any Carb guru's out there able to provide input to solve this dilemma.

I decided to check the idle jets one more time. Even after rebuilding the both carbs, I found the idle jets on the right carb hopelessly clogged. Compressed air wouldn't dislodge the clogs, so I used a small strand of copper wire to unclog the jets. Runs great now. When trouble shooting a problem, I always (most times) check the easiest thing first. Idle jets are easy to remove (I've had lots of practice) so I usually go there first. The car seems to be running good now but I'll take it on a drive to make sure. "Check the idle jets"! I'm thinking, fuel injection might be nice. (IMG:style_emoticons/default/biggrin.gif)
