can you tell me the exact ignitor that you used? i have raced mr ninjas for around 2 years and i thought that i had a bad plug, but my ignitor wasn't strong enough. i use a hot shot2, burns really hot and works great on mr plugs. seriously, i thought i had a bad one out of the package. i changed the battery in my ignitor to a brand new d cell and it still wouldn't glow, tried a friends hot shot and bingo, it wasn't bad after all.
