200ci Crank pulley too far in

[drag-200stang]

You have to use the big thick washer. When the damper is tight against the stock sprocket, the end of the crank is close to where the washer the sits, it almost bottoms out. You need a spacer to make it right because of the thinner new roller chain sprocket.

What is the OD of the balancer hub that presses up against the timing sprocket?

If the OD is more than 1.750" then use McMaster Carr carbon steel shim number 3088A518.
It is 1.25" ID x 1.750" OD x .125" Thick

Package of 10 is $14.85

You will have to cut the keyway into the inside of the shim.

You need to be sure that you need a .125" thick shim.
If it is too much then the bottom pulley will stick out too far.

The next thinner shim is .093".
Part Number 3088A489

They make those shims with keyway

Just to be clear, the spacer needs to go between the sprocket and the damper.
