Peter, John, et al,

 

Spark Plugs:  I use Denso Iridium IK27's ($12 each, www.sparkplugs.com ) and I am pleased with their performance even if they are moped plugs.  The gap is a consistent .032.

 

Warning:  I once used PermaTex silver goop, advertised for plug anti-seize, and found it fouled the plugs badly, quickly and irreversably.  I had beneficially used the stuff for the exhaust pipes slip fit and noted that it turns to a very thin penetrating liquid at high heat leaving a deposit of the silvery stuff behind.  Good for the exhaust, bad for the plugs.

 

I currently use the standard Champion anti-seize with no problem.

 

 

 

I'm the one Colyn mentioned with Lightspeed Ignition.  I had three separate problems early in the installation. A overheated processor box mounted aft of firewall which failed.  Added cooling fan and drilled some holes in the heat sink has been fine since. Bad coil replaced.  And one other weak link that has not been mentioned, a spark plug which failed.  These plugs are Honda motorcycle plug which Klaus uses because of the long reach and bushing size requirements.  They are not robust like aircraft plugs and do not go through quality control the same way.  Klaus has been looking for other sources but the small production runs limit things.  Maybe if everyone on the LML buys one. :) Klaus supported his product well and I'm pleased with it.
