I just got a savage 25 and it starts up no problem but when i hit the throttle it goes no where. The engine revs like crasy but nothing happens but if i pick it up off the ground i can see the drive shafts spinning so from the outside everything looks like it is working correctly, internally maybe another question. Any one have any ideas?

clutch.....

stripped gear maybe

or the diffs have gone...????.... check spur, check clutch, if not diffs...

hi do ya ear any weird noise coming from diffs , i had that problem on my savage but i ran full throttle into a ski doo and my gear in my front diff broke but i was still runing on 2x4 ,so if you see the shafts moving under to the diffs its not the clutch ,must be in the diff ,but I'm no expert
