Thrust issues with AFR gauge and Brawler carb

I’m in a Love/Hate relationship with my AFR gauge! So I pretty much agree with Tommy, if you are happy with how it runs and drives, then maybe just be happy! If it’s not pinging, smoking, bogging, stumbling or stinking…then be happy. As for the plugs, if those plugs have been in the car a spell, then they don’t look too terribly bad to me. If those are after a few miles, then maybe it’s time to take a closer look. Otherwise be happy.
Just my $.02
