Looks like it was run with the bolt and pulley loose and chewed up the pulley key slot. You don't really need the key to be perfect as long as the bolt is properly tight. So I'd say put it together (with new pulley and key for sure) and would be OK to run. To set timing, find true TDC by probing in cylinder 1, then offset the marks on the pulley if necessary.

thanks,

Yeah when i took the pulley off it did something with the timing

can you be a little bit more explicit

ya thats fine.. just be sure you still have the square key that goes in there and if its rounded any then i would get a new metal key for it. if its rounded and you put it in it could wear even more. but a new key should hold good.

After you have everything together, before setting the spark timing check the pulley alignment. Take #1 spark plug out and insert a suitable metal rod into the hole so it touches the top of the piston. Rotate the engine by hand until the piston (and thus the rod) is exactly as high as it will go. This is TDC. Check that the single mark on the pulley lines up with the plastic pointer. If it does not, remember the difference between true TDC and what the pulley says, the same difference will also apply to the BTDC marks you use to set the spark timing.

I would really suggest a new or good condition used pulley as if it has been run loose the hole in the pulley and/or the flat part that meets the crank may be wallowed out and it may be impossible to get the bolt tight enough to keep it from moving again.
