Been having issues with my kilo tt.

I've switched back to my kilo from my 725, and also put on a 1/8th 17t cog onto my kilo tt along with a 1/8th chain. However the chainring on the bike is a 3/32, I've read that I shouldn't be running into any issues, but when I start from a dead stop and on the downstroke (right foot for me) it feels like it drops down and there is no forward momentum. I know its not possible that the wheel is losing traction, but I also can't think of an issue it could be with the drive train.

I'm wondering if anyone had any clues as to what this issue could be and how I can fix it, I'd prefer not to have to buy a new chainring to match the 1/8th to match.

Thanks
