[Intuit]

You have to lock the tensioner pulley in the release position. There should be plenty of slack for sliding the belt over the pulleys before releasing the tensioner. Recall the tip I mentioned at the beginning of the thread... <<You may keep finding that your timing is off the mark by one tooth once you snug things up and even before you turn it over. To counter, you may have to intentionaly set your timing off a tooth before snugging things up. The "backside" of the belt going straight from the cam to the crank is what you'll want to make sure has zero slack.>>
