    Ok recently my Aero has started popping when I back off the throttle in gear. What causes this?

    • Usually a lean condition if it just started could be an air leak

    • Air leek in fuel line or carb?

    • Homemade pipe mods.

    • Check your exhaust gaskets

    • Could be carb boots or loose exhaust

    • Or what Gilbert Anthony Rangel said bad gaskets

    • I use 87 octane and put 93 octane in it once. That one time I filled with higher octane fuel it popped a lot. Went back to 87 octane and no popping since.

    • Thats what I did Casey. I put high test in it and thats when it started.
