Had a small dimple in the knurling, not a huge deal. Awesome price for a part thats gonna get coated in diesel sweat and you will hardly notice and hopefully only use a couple times. Broke plastic tit 2 times during my rebuild, so this will float around my tool box till I rebuild my motor or need to reset my timing. Added 50hp, so with this and the pump pin I'm at like an additional 2000 hersepewors... Lol.. Definitely won a customer from the big box names.... If you guys want a test dummy for some more awesome parts hit me up!!!! I'll shamelessly rep you guys, wish it had some cool decals or swag to rep
