Jim, same two screws I used for my sensor. The bracket was really difficult to make though.

More run time on the Saito 150 conversion. Today I got 7200 rpms with no tuning on either the high or low. I'm taking things really slowly on this, meaning not changing a bunch of things without a good reason. Getting a tach reading was tricky because the shop lights make every RPM read 3600. It sees the 60Hz flickering. I got around that by dimming the basement lights and shining a flashlight into the prop arc. Irigged a home made engine exhaust vent system in the basement made from a big shop vac because it's -17 degrees in the garage.

My first observations are that the transition from low to high rpm is ok, but when closing the throttle, even gently, the engine quits. Also, it takes an electric starter to get it goingdoesn't want to start by hand flipping like a 2 stroke would.this is after choking with evidence of gas wetness afterhaving done so. Any ideas?
