curious cam sprocket wear- 340

Hughes engines make a nice retainer that works with a fuel esoteric or not. Not a lot of money. Just a thought when you put it back together.

If you are talking about their "nose extention" for adapting a non mechanical fuel pump cam to a mechanical fuel pump, I wouldn't recommend that one. I don't see how one small block of aluminum can replace my keyway. I had to make improvements to mine to make it more durable... POS....

Instead of sending me the right cam, they got to charge me an extra $30 for an "adapter".... Haven't used them since...
