Guys, I think this is great. Most people on this forum are your hardcore type hobbyist. Younger folks getting into the game are clueless. Heck, most of your older car guys just get a motor, start it up and set it at 8 or 10* and it's good to go. How many times have you heard "I could never get it to run right, that's why I went to fuel injection, best thing I ever did." however, young guys like phone apps and they can understand the timing curve eventually. To get someone to understand timing tape, piston stops, timing gun, weights, springs, vacuum adv. is just too much. They just want to drive em.
