Alistairs, I did notice with the coil I built myself that it fired quicker. It still had a bit of a lag, but nothing like the factory coil. Perhaps the lag is inherent to the Lemo? I put the same basic coil in the Lemo that I put in the Russian 91. With all the weird issues I've been having with the Lemo tonight I just put the Russian back in action. Futz with the Lemo tomorrow.
