Michael,
Be very careful with the Aerocarb . It has a tendency to jam at low throttle settings such as late final and it jams harder when you try to open the throttle quickly as in a go around.

Noel,
I could not appreciate if the popping changes rate with RPM during the ground running operations. My attention was really focused on RPM, EGT, and CHTs at the time (trying to fine-tune an Aerocarb for first flight operation). At the time I was aggressively changing RPM but was on the local frequency - traffic transmissions were too short in nature to notice a change in popping. When no one is transmitting everything is normal.
I will listen to ATIS continuously on Friday while running the engine and report back.
Thanks!

This is Thursday morning so I’m taking a chanced you haven’t gotten any answers or even a fix yet.
First thing is, does the popping change rate with the rpm of the engine?

Subject: Radio popping
Hey guys,
I am doing some initial ground rounds with my Jab3300 engine and was noticing a popping noise in the headsets - while receiving ONLY. The popping noise is pretty bad. At first I thought is might have been the other aircraft's radio (flying in the pattern), but after tuning to a local ATIS I got the same popping sound. I am just trying to see if it might be something obvious, something that one of you might have experienced as well? It does not happen when the engine is not running. I am thinking that maybe I should start out by buying resistor plugs? I am NOT an electrical person at all... but I did try to wire per the Aeroelectric manual.
Any thoughts?
