Pre Dye Carter Comp fires after completing pump stroke.

So apparently if a Carter is assembled incorrectly it can auto fire when forward stroke of the pump handle. How would one fix this?

I recently sold my Carter Comp to a member and he is having this issue unfortunately. I don't have the marker in hand to figure out the issue. I had been shooting the marker for a while without issues. Is there something to look for that causes this issue. Could it be a sear issue? What causes this?

I want to get it worked out for him.

I believe the fix is all about alignment of the snub or receiver relative to the frame. You want to loosen the clamping set screws and ensure the snub is moved towards the rear of the gun, flush against the valve body. I think I'm remembering this right.

The snub acts as the travel stop for the bolt, so if it sits too far forward, it allows the bolt to over-travel and the sear contacts the trigger early.

Awesome it may have just loosed up just from playing I suppose. Maybe a lil lock tight may help keep it in place. Thank you for your help. I figured it was something simple. hopefully this fixes the problem.

[BOOSH!]

If that doesn't do it, you might want to take it apart and look at the inside latch of the sear. It's an old gun and those sears can get wear on them like anything else. If it has any kind of angle on the Inside/Latching point of the sear, it will need to be replaced. The inside/latching point should be a vertical cut (straight up and down)

Don't confuse the inside latch with the outside of the sear, where it first makes contact with the bolt. The outside of the sear should be rounded.

Ended up being an adjustment issue. Loosened it all up moved stuff around until it didn’t fire on the forward stroke and it was good to go. It’s not like a phantom ware you want everything tight and flush the carters are a bit sloppy.
