if the problem is that your chain is slipping can you tell if its the cog or the chainring(<-which seems unlikely) thats not catching?

and when you say a little tension, do you mean when you use reverse pressure as in backpedaling?

one last thing, does it only happen at just the beginning then catches or is the wheel just still spinning while the pedals are locked?

can you take an actual picture of your bike? everyone would be able to help a lot easier then - particularly your chain
