I bought a Crosman tyro as an upgrade for the kids, they currently have a crosman 760 multipump. Very small and light rifle, great for a starter for kids. The tyro is a Christmas present,so, to make sure its broken in, i put a few pellets through it, after 200, i still wasnt happy. The trigger, dieseling and lots of flyers with at best 100mm groups at 16m. I stripped it down, the trigger has lots of burs and twisted metal work, my fault for buying a Chinese made rifle, but i have a soft spot for crosmans. After much filing to square off and smooth out contact points, better lubrication, its working way better now. The piston grease smelled like normal petroleum grease, hence to constant dieseling im guessing. After cleaning everything off and relubing, reassembly. Back on the range, no dieseling at all now, smooth consistent trigger. After 40 or 50 shots, im now punching the same hole over and over. This is why i like crosman i think, low cost but with a little TLC, become a diamond. Green lines in photos are where the trigger needed work    ------------- Diana 350 Magnum And a few others |
