Question about Crosman (4032)
I have a Crosman 140 which was fully rebuilt a few months back and I'm concerned about the adjustment on the pump rod.I notice when I pump it quick it does not auto **** but on slow pumps I can hear the air **** in with each stroke.When it was rebuilt the nut at the barrel end of the pump rod was left loose "should it be loose or locked down tight?" and as a reference point how much of the felt should be seen in order for the pump cup to pull in the right amount of air? The gun holds pressure and is strong but as I stated I have to pump it slow.I can only see about 1/8" of the felt at the end of a opem pump stroke.
Contact Alan at ABairgun.
I own a Crosman 140 (c. 1962). The nut should be tight.

My gun is original since I got it back in the 60's and about a 1/4 to 3/8 of an inch of the felt is visible. It has never been adjusted and works fine. Keep it well lubricated with 3 in 1 oil or gun oil.
