My engine was built by Hayes Rotary in Washington. He has retired now, but he 
opened up my trailing plug holes for better spark plug effectiveness in case 
of a leading plug failure. He thought it would be safe for an aircraft even 
tho a small bit of compression might be lost.
I have not flown my engine yet, but in the initial ground run while testing 
the B controller, I performed the coil cut out  test and they seemed about 
equal, that is a slight loss of RPM. Sorry, I was too excited to have my engine 
running for the first time to record what the drop was. But now reading that the 
drop is negligable without increasing the size of the hole for the trailing 
plug, I would nopt have had it done.
