I have a 362 Crosman which I love, I stupidly put some gun chamber lube in the air tube, the gun would not build pressure, I called Crosman and they gave me a tip on what to do, it didn't fix it , tried an alcohol flush, didn't work, now I have air in the chamber that I can't get out, they told me to cock and fire without any pumping, I have done this several times, will this solve the problem? I don't really want to have to send it in. Thanks
