Hey, I finally was able to find some time to get this old motor started and after replacing the stator and power pack it now sounds like it’s hitting a rev limiter when I start it. I’ve never seen this before so am somewhat at a loss for what to do. When I pull the top cylinder plug it will run better but nowhere near a good idle. Short video is attached, didn’t want to run it more than 5 seconds like this. Carbs were also cleaned recently. Thinking this is definitely an ignition issue.
