49cc bogging down when "recelerating"

[smicsmit]

I have a 2017 Bintelli Sprint. The airbox was broken when I got it, and I bought a new carb that came with pod style air filter. I've gotten it running fairly well... Bought a set of main jets and experimented. It has an 88 main jet installed right now, which gives me the best performance, but the next size lower I have is an 80, and that's too lean.

With the 88, it accelerates well, and gives the best top speed out of the jets I have. The only issue is that if I let off the throttle to slow down (like to make a turn), then open the throttle back up, it bogs down slightly before catching up again. Does this indicate that Im too rich?
