No, I didn't feel we needed the unlimited coil. I did pull the limiter tabs on the low and high speed needles, and touched up the velcity stack with the sanding wheel. Haven't done anything to the carb as of yet, may not. I actually would like to try a HT1 on it.
Basically, added a port to the muffler, set the squish, ported the cylinder by opening up the bottom transfers, cleaning and matching the top transfers, widened the exhaust, widened the intake and lowered it a few degrees, and then added boost ports, coming from the top of the bottom transfer. Should be sucking plenty of fuel, which makes it pull hard for a "still tight" engine. That video was only the 3rd cut that saws ever made.
