Wow those plugs are really really clean for an engine that wont idle. I would expect carbon fouled plugs.

Anyway, from your plugs it looks like you have too much timing. Looks like your air fuel ratio is decent, you could probably stand to richen it up a little bit and see what it does, but I doubt that would make your problem better.

Judging by the fact that you're not overly rich, its probably not either of these problems but it might be.

1. Not sure if this was mentioned before but have you verified that the metering rods are staying down at idle?

2. Are you sure that you put the metering rods back in? I've seen people forget them more times than you'd believe
