Thermoquad jetting help?

I agree with rumble, your primary should be around 98 with around 128 or so secondary. These carbs were jetted back in the day for 100% fuel ... not 10% ethanol so you might be close or a bit rich. Plop it on with fresh plugs and see where it's at, there are a lot of other tuning that can be done before changing jet size like sec air door, removing the choke will lean it a bit. If your still rich you should be able to find jets for it.
