94s should be cycled very quickly....doing so will preclude jamming....running the lever slowly in a 94 invites jams....
That's been my experience too. Which is why I don't own any Winchesters anymore. That, as far as I'm concerned, is an unreliable firearm and has no place in my arsenal.
My factory Marlins don't jam. The one that's customized has some bugs that's I'm working out. Which is another nice thing about Marlins....a novice can take them apart and put them back together without too much fuss at all. Not happening with a M94.
You really under estimated the ramifications of the boondoggle you have just perpetrated!
