The current taps I have aren’t spiral tap but they are through taps so I guess I can start with those and see how it goes. I’m not going to be tapping a million holes anytime soon so I think I can suffice for now.
Here is a video of the exhaust, I would take a video of the carb side but it’s currently snowing and 25 degrees so it would take a year for the engine to warm up lol
