I pull my plugs and clean them at every oil change (typically about 35-40hrs).
Of course there are always lead balls, particularly in the lower spark plugs.
(I lean aggressively on the ground and 75-100 ROP in the air.)
I also fairly commonly see material lodged in the spark plug gaps of the lower plugs. I assume this is lead as well. The last time I cleaned them I believe there were at least 4 bridges formed in the lower plugs. These are REM37BY plugs so if one gap is bridged, the other may not be.
What is surprising to me is that the engine runs perfectly normally with normal RPM drops during mag checks despite this finding.
Do you think these plugs fire normally with these deposits on them?
Do you guys see this accumulation?
