The parts I imported from Alan at www.Abairgun.com<br /><br />The problem I have now is that after a few shots the pump washer seems to get locked inside and then ceases to pump and the handle becomes free.<br />I am not sure if this is due to heat caused by the Pump and wrong oil combination.<br />ANy ideas on that.<br />Thanks<br />John - IndiaJohnnoreply@blogger.comtag:blogger.com,1999:blog-2378835029459742413.post-70711332535460022992009-01-10T20:57:00.000-08:002009-01-10T20:57:00.000-08:00Nick, my 147BP only has a rubber flat washer as th...Nick, my 147BP only has a rubber flat washer as the air transfer port seal.
