trying to tune my new /6 engine

One thing I recommend different than the videos. Watch them first. You'll see that float adjustment is one of the last things they do. IMO, it should be the first. If the float adjustment is wrong, the very foundation for all the other adjustments will not be right. Good luck.

Yes, the float adjustment should be made first. If it is too high, you will run rich. If it is too low, you will run lean and it will delay the fuel signal when applying the throttle which causes it to bog off the line.

I would recommend, first adjust your valves. Second, check for vacuum leaks from the carb to the intake and head. Third, make sure that your timing is correct. Fourth, then try adjusting the carb to see if you can get a smooth idle.

ps. Don't forget to adjust your accelerator pump to the proper spec. That will also cause an off line bog if not correct. Many people forget to do that.
