Your mods wouldn't cause you to run rich on a stock rebuild and light mods. Check your plugs. How are your plugs gapped? How old are your plugs? Check your front o2. How did you do your motor break in? Just humor us and check your coolant and your oil for run on. This may sound odd, but take a quick sniff of your exhaust, does it smell like, coolant, oil, or just fuel?

Regardless, check your plugs and their condition. Note any buildup on them. Tan/light brown is a good color for the tips to be.

 

just a stupid silly question, but do you have a check engine light?
