Quote: Also note that every time you change the crank sprocket key way you have also changed TDC postions so TDC would need to be found again.
But remember about moving the crank keys..you gotta find the new TDC again, a bunch of people dont, its not worth the trouble of doing it then IMO.
You got me baffled here , maybe i'm missing the point somewhere (most of the time ) , but why would moving the crank sprocket loose TDC? , these multi keyed sprockets are meant to be moved around to help aid in degreeing the cam , just asking.
