Revainrating 3 out of 5

I had to go back to get ignition parts

I bought this as a backup in case one of the motors failed (it happened twice in 21 years). So I wanted to test it and see how it works but the holes in the manifold didn't match. so i return But after filling I can see where there is a thicker foam gasket around the rim on this unit that needs to be compressed more than it can allow, maybe the problem. My old one has a thin seal. So if you buy this and can't line up the holes, take a sharp knife and cut the gasket in half the width.

Pros
  • . Easy to use
Cons
  • Band
