Perfectly good starter
Style: S114-823S
Though I'm sure this was a good starter it looked great I'm sure it would have worked perfectly however because of some problems with my engine and bolts being stripped out in my motor I had to return it but there was nothing wrong with the starter just wouldn't fit

Do not buy this junk
Ordered on January 31 installed it on March 19. I’ve started my sick times with it since and now dead absolute junk. I would highly recommend staying away from this.
