Thought you guys would like to see Saito 150 gas conversion #2....first run. Walbro was balky at first, so I just set them at the factory 1-1/4 turns out and you can see the results.

This conversion's hall sensor and magnet are a little different than the first one. This was made by CH Ignition. I like the vertical concept for the hall sensor bracket. The magnet is mounted parallel to the crankshaft in the ring, which is adjustable (timing) because it's only held on by a couple of setscrews. Good job CH! Just make the sensor bracket a little shorter for Saito and it'll be PERFECT! The bracket wouldn't fit the engine unless I placed two washers UNDER the bracket. Otherwise, it hung down too far and hit the front bearing housing. The sensor is held onto the bracket only by JB Weld. Working so far.

The good part is this setup is getting 8500RPM with an APC 13x8 prop (pattern). Seemed like it had a lot of compression when working with this engine on the bench, so I guess I'm not that surprised.

Here's a couple videos:

EDIT 7/10/2010:
A sharp reader spotted the fact that 8500rpm was slow for a 13x8 prop. Good catch. It was a late-night typo. The prop is a 16x7 pattern APC.
