if the pulley wobbles without a key, then it's likely that it has deformed to accomodate the slop in the key. if you're not planning in changing crank and/or engine, then at least dump the key AND the pulley as they're both stuffed.
OT but relevant: we used a very old diesel engine to pump water up to our dairy - was big old circa 1940's southern cross single piston workhorse that ran at a few 100 RPM. It used a key about an inch thick and flywheel required two adults to lift from flat to vertical. So well built, you can still get consumable parts (rings, valves, injectors) for them... anyway
first time fired up in anger, key was 2nd hand with rounded edges and crank/flywheel bolt wasn't tight enough (who has a spanner capable of tightening a bolt approx 12cm diam?). Key was broken before engine got up to speed and the free spinning flywheel undid the nut and rolled into paddock (could have been into the dam so it counts as lucky).
moral of story: the key MUST be an exact fit and it's important that pulley/crank bolts are tightened up to (and beyond) factory specs.
