- Missing and dried out old Gaskets have caused numerous problems. They're very cheap! Replace them!
- Gaskets have to be cinched down tight to function properly. Sometimes after they soak up gasoline, Jets become loose. Some people recommend retightening after in use for a week. The red fiber gaskets are difficult to seal and I've seen cases where they are too thick. So, I have switched to a new carburetor gasket material that is now available. They are thinner, softer, and work better for sealing the jets. They are white or light blue in color and I think they are made from Neoprene. I have had no problems getting them to seal well.
