If I am just using it for a test stand would it matter what size? As long as it a neutral balanced one? Whats the difference in application from the 143 and the 130?
The teeth are on the outside of the flywheel. they are spaced the same distance apart, so if you have a 143 tooth flywheel you have a bigger cercumfrance, if you have a bigger cercumfrance, your starter won't line up with the teath. Heck the flywheel might not even fit in the bellhousing that you have.
