I'd definately bring it back to the shop as soon as possible. They should double check the timing marks.

That's what that second belt is there for and it doesn't use timing marks. They may no know how to time it. It can be 180 degrees out and do that.

HT hit this one on the head. The balance shaft is 180 out. They should know this but there is a plug half way down the block, line everything up remove the plug and insert a drill bit in the hole, if it can't be inserted at least 3", the shaft is 180 out.
I'm guessing your old belt broke, this usually doesn't happen on maintance replacements........

The counter balance shaft is run off the oil pump sprocket. This view may help.
When I get one with a broken belt I just spin the gear hard, it always winds up with the weight on the bottom. You can even rotate it around to line the mark up again and you can feel the weight on the top wanting to roll over, which would be off. Using the drill bit method is 100% but if you've done a few spinning the gear works fine an is faster.....
If you want to use the plug method, just follow the balance shaft down the side of the block, it's about half way down, it always seems to be a PITA to get to.....thus the spin method is perferred....
