Jon, I used to pride myself on rebuilding to excellent working condition all Model B's. I was only fooling myself because 30 years ago a 235 usually had the original carb. Not so anymore, I sent a thread a few days ago about my 54-3100 carboning up new plugs within a half hour. I rebuilt the carb twice, not a leak anywhere and vacuum perfect. I'm a little afraid to start it up. Using AC-45's, third set. Geeze, I don't know what I'm doing wrong. Ed
