I would have been done with my whole motor build hours ago but my goddamn timing belt keeps wanting to jump teeth. I was doing the test rotations to see if it lines back up at TDC after 6 rotations and whenever it feels like it, the belt will try to jump a tooth but if I back it off it will be fine and keep it's place untill it feels like doing it again. I've been up for about 28 hours straight and I'm starting to lose my mind. What the fuck gives with this belt problem?
