[br]So if the question is weather or not correct spark placment helps just get a stun gun for 20 bux and make a spark card that runs the length of the chambe and all problems are solved. If you're serious about getting properly applied spark energy it's the only way to go. If two sparks gave you that much more hangtime think of what 20 or 30 sparks could do. Of course you get exponetialy deminishing returns with each added spark over 3 or so.

Great theory. Care to test it?

One problem with a spark strip is that the strip itself interferers with the propagation of the flame front.

here is something to keep in mind since it is cold. Durring the first shots, the chamber i bet was cold. after those shots that chamber warmed up. since you said you meter with a syring i assume you use a liquid fuel. most liquid fuels i know of will vaporize more readily when heated or warm. so the longer hang time shots could be due to better fuel mixing making a faster flame.

Just a thought.
