Can running rich cause knock?

[94EclipseGST]

This may seem like a silly question, but here's why I ask.

I just had my Walbro 255 installed. After install, I was running extremely rich--I was bogging down and couldn't rev above 4000 RPM's. I noticed too that I was knocking like crazy. I thought, how the heck could I be knocking when I'm running so rich?

Anyone know if this is possible? I began to lean it out, and that helped some. Also, is .96 02 too rich for a 1G at WOT?

Thanks,
Steve

Yes, too much fuel can cause knock. Every car is different but .96 for my car is pig rich. Id try leaning it out some more

It can, in some situations. However, you need to be REALLY rich for it to occur, and not all setups or all cars will do it.
