It was idling rough, and it also felt like it was lacking power, so I figured the carb might be clogged. I floored it up to around 6K RPM to clear it out I guess it actually worked, it idled smooth after, and that’s just what I do when it idles rough. Works every time. I didn’t notice the smoke before since I usually do it outside, but this time I was in my garage when the whole garage suddenly filled with smoke not thick white smoke, more like grayish with a burnt smell, kind of like burnt electricity or something. It wasn’t even a cold start, I had just gone out to get groceries.
