The engine pulley was next on the list, i bought a taper lock one but this came with a few problems, The engine shaft was geared and it was also not long enough the slide the pulley out to line up with the transmission pulley. I turned a new belt groove first
A small test for alignment.
The above image shows the issue. the taperlock bush is an 1'' ID but the shaft was about 11/16" so I made a bush.
The first bit turned to 1"
Then I bored the inside out to fit tightly over the engine shaft.
A couple of grub screws with tapered ends screwed to clamp the bush.
