Chain skipping a tooth on a new chainset, chain and sprocket. Help?!

Is it slipping over the chainring or the sprocket? Sorry if I missed something in the OP.

A SS ring will have taller teeth. Also I found finding a chain tensioner that actually worked something of a minefield when my 29er was SS.

Tbh, while riding it (the only way of getting enough pressure to make it slip), its kinda hard to tell whats slipping. But after replacing the sprocket, I'm kinda sure it ain't that.
After staring at this bloody thing upside down turning the pedals for a couple of hours I'm starting to agree with you on both accounts dude. Hpefully a larger SS chainring will help. Any recommendations for chain tensioners?
