I ran a 46 on mag with some props but can't remember what the #s were now. I didn't have a muffler on the 42 durring this first run. Maybe that will improve the numbers some. I worked on a rotater manifold tonight. Almost have it finished. If you notice with the stock manifold the adjustments point at the prop and the throttle and choke isn't a straight shot either. Solving 2 problems at once.
The ignition is built by Roy also.
He did the ignition, hall setup with led indicator to show power, mounts, prop adapter and all. Nice work. Check out the size of the ignition box. That's a quarter setting on it! Magnet is a nice setup. Clamp ring on the hub. Just rotate it to where you need it and tighten it up.
