Re: Damaged valve

that doesnt seem real bad, does it ride past the seal? if not, you can file it smooth and use the valve. otherwise, lap the new valve to make sure it has a good seat and you should be pretty much set.

Here is a demo of valve lapping. They are using a car engine in the demo, but the operation is the same.

Re: Damaged valve

your cotter/valve keeper did that damage. they do do that sometimes. as they say, you can still use it but get rid of any high point now so the valve will come out. use a small file to rub down that area then you should be able to pull it through.
