Either way, it has enough fuel.

10:1 is rich.

10 to 1. ok so why do ya think it is detonating? it does it at anout 5000 rpms. would octane level have anything to do with it?

Pull some fuel out of it. Rich mixtures detonate too.

Plus depending on what wideband it is - 10:1 could be the furthest it reads. You could be in submarine arfs

i aint sure about the timing, but now at 4500 it seems to cut out and power down no matter how much gas i give it.

You sure its not blowing the spark out? You are leaving a lot on the table with <10:1 afr

Not knowing what the timing is though is a problem in itself.
