Had my Pinty Pup lose air a while back & it wouldn't take air. I dry burnished the poppet/valve & that fixed that problem. I went to shoot it yesterday & it was empty. Once again it just blew air out of the barrel & would not seal. I burnished it again today with valve compound & also polished the valve. No luck! I've tried everything I know including cocking the lever & loading 2 pellets in the barrel while filling but no go. I have an email off to Pinty, to send me another poppet but I heard they don't carry spare parts. Any other suggestions?
