Not sure what you mean by "a piece of metal on the basket pulley".

Basket pulleys are a little temperamental, if the set screws become loose, it doesn't take much to ruin the bore.

I guess the first thing to check is the key-ways in the basket and in the crank shaft, If they are wallered, you're going to have a hard time keeping it tight.

Then check to see if the basket fits the shaft well.

If the keys don't fit well or if the basket is very loose on the shaft, I fear that you will need to repair or replace the worn parts before it will stay put.

I'm guessing that you do have set screws in both holes in the basket?

IIRC, the wiring on a 122 is braided, but is still much better than the wiring in the 1X6/7 series tractors.
