    ‘82 GS 1100G mystery plug

    Why does the #2 carburetor have a little black plug in the small jet access (next to main jet in bowl)? The 3 other carbs do not have this....I can’t seem to get the #2 cylinder to fire. Engine starts and runs great, but the #2 exhaust remains cool, and pulling off plug wire while running, makes ZERO difference in RPM. When I place the palm of my hand over the intake of the #2 carb, RPM’s INCREASE dramatically, whereas when I do that to the other 3 carbs, the engine nearly dies. Carbs have been thoroughly cleaned, all orifices blown out with carb cleaner and shop air, visually balanced and physically balanced with gauges, but #2 gauge shows ZERO on the balance gauge. Compression 130, plug fires healthy blue spark, just can’t put my finger on the problem. I removed the little black plug from #2 carb, but still no difference.
    Spark plug shows a lean condition when I pulled it. This has been a very fun project for me, and I’ll eventually figure it out, then post what the problem was....Cheers!

    You might want to go through the carb rebuild tutorial linked in my signature. Regarding the plugs, each carb should have one, assuming you are referring to the rubber plugs over the pilot jet passage.
