FBO Ignition

I bought 2 distributors and 1 complete ignition kit from Don. Everything was good except 1 distributor where he had the pick up at about .100 and on Dyno day it wouldn't fire off. Brian at IMM engines Quickly found the problem and it fired off Immediatly. There is also a VERY funny story behind a spark plug being left out when spark was checked again.........I will leave it at that Brian!!! Still laughing when I see it in my mind........haaaaaaaaaaaa
