Ok so heres my problem. I've got a Snowbird S-228. I was having problems with a very tempermental engine, so I desided to swap the engine. The pulley wouldn't budge, so I thought a gear puller would pull it off without a problem. I was wrong. I got it off, but it was bent in the process. I tried my best to straighten it out, but its ruined. I need to find a replacement. I think the pulley is called a stacked pulley. Does anyone have any parts that might fit or know of a website to search for parts like that. This snowbird is probably 25+ years old and Idon't even know who makes it.
