How is the idle when at full running temperature? If it still wanders I usually look first for vacuum leak on the carb to intake side then look at cleaning the carb and the idle circuit inside it and adjusting the fuel air mix screw after bringing the idle down to just about quitting after it’s warmed up to full running temperature. Then when air fuel mix is dialed in bring it back up to normal idle speed. If it’s still acting up then look at if it’s got a stock air filter and clean filter, or if it’s got an after market high flow, then check the exhaust side. With the carb apart is also when you look to see if it’s been rebuilt and the quality or the rebuild job. When stock and all clean these things are pretty solid. But dirty and modified then it gets to be fun times diagnosing what is causing it.
I got the idle dialed in and sent her home. Still had a little surge but I think it needs run!!!! And then see what she’s doing. Before tearing her down.
Issues with one of the coils, seems to only be running on 3 cylinder and bad/low spark ont the 4th
