I honestly don't know. We fueled up the plane, primed the engine, put on the glow starter and turned the prop with a chicken stick and it snapped almost in half. I had the prop resting where the instructions said to put it. I'm not sure why it broke. Maybe because it was a brand new engine, and they're hard to turn over?
Can you link me to the right size spinner and a backplate? Or do the spinners come with backplates?
The spinners come complete with a backplate. The Avistar calls for a 2-1/4" spinner. You are also going to need to get the correct spinner adapter. They are different for each engine. If I remember correctly you have an OS 46 on your plane (if I'm wrong please correct me). Here are the links:
