Noise Posted December 5, 2014 Share Posted December 5, 2014 Yer the best thing is to put oil in it and leave it to soak through over time might even take a few days to free it up then start knocking it with a mallet as Drew said, take care not to go mad and snapping the fins off the barrel, also heat up the barrel not the piston.

lascellebubear Posted December 5, 2014 Share Posted December 5, 2014 Look through the exhaust exit and push a screw driver up pushing the rings in so its easier for it to come out Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
