Been working on my winter project (B style intake, ported bores to a Demon Jr 525) & finally got all the parts & time to put it back together. Problem is she won't fire. Suspecting it must be something I just did (usually is isn't it?), I went over everything & don't see anything obvious. I figure it's gotta be fuel, spark or compression. I didn't take the heads off, so rule out me messing compression up. I just replaced the carb so fuel seems likely. But I wanted to also confirm spark. I have a 57 dizzy with a Pertronix, & that was working fine. I didn't remove the dizzy or plug wires when swapping intakes, so timing wasn't disturbed. I did relocate the coil (Flamethrower coil). Another clue is I have been chasing down intermittent brake & tail light issue (success on that one) while I was saving up to buy the carb & parts. So had the ignition switch on for periods of time without the engine running.

I have searched the site & saw that it's possible to burn the Pertronixs Igniter 1 up by doing so if the Hall switch happens to be closed. I contacted Pertronixs & they told me how to check by using a meter & sweeping the magnet by the sensor. So it failed that test, I think I found the issue, & buy an Ingitor 2 so that won't happen again. I decide to also buy all new spark plugs & put them in with the new Igniter. I put in the new stuff, have 12.6V to the positive coil terminal, & still nothing. I lay a spark plug on my exhaust manifold with plug wire attached & see no spark when turning over. Also try a timing light & see no flashes of the light. I should see something I believe with either of these two methods. I have a good ground to the Igniter mount plate as suggested by Pertronix.

Ideas to help me chase it down would be appreciated. I think it has to be something simple & likely self induced.
