New timing belt jumps teeth

[Blake]

Thanks for the response but I physically counted the teeth on both belts.
I checked that the belt was sitting properly in every accessible gear tooth.
Yes, the old belt never slipped and was still in proper timing, however there was alot of oily mess in there and the old belt had some its fibers sprayed all over the bottom areas.
I did clean everything which is why I suspect it loosened up the crank gear because the grunge was keeping it tighter.
