or more like tried to? frustration is being polite at one point thought it was the pump head seal but not so sure now? taken apart old exhaust pin a bit gingy and sticking so put new one on , all bits cleaned and put back together - still wouldn't take a pump , bits taken off the back and tried(mattyboy) suggestion - gave it a pump and the exhaust valve didn't even move , time to open a beer and sulk with a fag. thought this ain't gonna beat me so gave it a pump and pin still didn't move so now anger kicked in and gave it a couple of rapid pumps and hey the exhaust pin shot out - bit happier knowing at least it was getting air through the cylinder but defeated i gave up and went on the pc and look for parts wondering if i could get hold of an original pump head but it's like an "itch" with the gun on the table behind me - you keep looking at it and yes grabbed it and smashed a few quick pumps into and thought hang on this is taking air in - pulled the trigger and a lovely big bang of air came out getting somewhere me thought - NOT tried it again and seems the exhaust pin is stuck out and air blowing passed it so gonna give my fridge a bashing and sod the gun till tomorrow
