guys, the bolth thing sounds stupid, a proper spark tester that will simulate running condition spark resistance only costs a few bux, and will give you the best result.

problem with testing spark the ghetto way: it takes 5K ohms of resistance for the spark to jump in open air, it takes 30,000 ohms of resistance for it to jump under compression in the cylinder
