I picked up this TO-20 about a week ago and finally had time to work on it this weekend. I was told that it hadn't been run for about 2 years so after checking everything over and topping off fluids I got it to start! I had to keep working the choke to keep it running for about 10 minutes before I felt I could step away and trust that it would continue running and even then, the choke was about 1/2 way out. Even though it was running it was running pretty rough. After looking at the carburetor and doing a bit of research I'm fairly certain this isn't the correct carb. I haven't pulled it off yet and can't see a tag on what's visible, can any of the carburetor guru's here give an identification?
