    what would you guys recommend for a spark tester? I heard a lot of talk about a good spark being able to jump 1/4 inch in this thread. handling the plugs (and their proximity to the block) is difficult while pulling it over or otherwise advancing the flywheel, etc

    soooo… I plan to buy a good spark checker and would like to know which ones you guys like the best.

    thanks!
