Hi Bill, Im having issues with my Duraspark conversion rotor for Fuel Injection. I followed the forum on how to build on with ford internals with the GM EST controller. I used all new parts and built my own. Im only able to get it to spark when i use my drill and bench test it. Im running my drill at a higher speed to spin it over but when i put it on the 345 and crank it it wont spark. Any ideas where to start?
