Looking pretty good now. I’m surprised it ran at all. I ran one most every day, several times a day, for about a month, with mixed results. I’m not a fan of that carburetor, on that motor. I had 2 with me. It seems too big, needing a lot of adjusting when changing speed. Found it easier to add or subtract a little choke than using the mixture screw.Here is a link to some of the ways I make gaskets. There may be something in it that you can use. https://youtu.be/I0FrFA__n00?si=JVhZgXtrIW7EXixc
