A little benji advise needed....

[Muddydogz]

I've got a transition Benji, rear safety. After about three or four pumps, then when I go to pump again the forearm really jumps out. Is this air between the cup and the valve that's not getting in the valve?  The shot power is good not great compared to others I have but it is accurate. Linkage seems tight also so I'm not sure what to look for.

 Could be the intake valve leaking, if the gun hasnt been shot for awhile, or has many miles,an alcohol flush may revive it , or clean things up nice for a reseal.
 Sometimes just working some oil through frees things up and will kep it shooting fine.

Get yourself some Secret Sauce. It's good for the pump arm pivot points & internals. A little goes a long ways. Try the alcohol flush as James suggests, then lube it up.

I'll try the alcohol flush as you guys suggested. This is a new to me rifle and it seemed a little dry. First thing I did was add the secret sauce. Thanks

Well today my 392 brought me here.  I hadn't shot for several months (less than a year) and things were just fine then, but today the hissing sound told me something bad happened.  What is this alcohol flush spoken about here?

I'm guessing a reseal will be next in order, but what about springs?  Replace them or test procedure?

Basically you would open the pump arm and inject about a teaspoon of alcohol in the tube ahead of the pump cup with a meat injection syringe. Pump the gun slowly until you feel like the alcohol has been migrated throughout the valve. Then stand the gun overnight. In the morning pump the gun and dry fire it repeatedly into a white cloth or paper towel and check the color of what comes out the barrel. Repeat the process until it comes out clean.
At this point if the gun functions as it should, the flush was successful and you can put some oil in it and enjoy. If it is not successful then the gun will need resealed.
That's how I do it... others may have a different way.
The objective is for the alcohol to dissolve and flush out any dried and thickened gunk from bad, old or wrong oil that has sat in the gun over time. It will not fix dried out or damaged orings.
