Question about Craftsman 25cc Gas Line Trimmer
There are check valves in the primer base assembly of your carb. They allow gas/air to flow in one direction but not the other. They can go bad and cause assorted problems, fuel movement to and from the carb being one. Remove the cover with the bulb and the fuel line to it. Liberally spray with WD-40 on the carb and into the fuel line itself. Put the bulb back on and "work it" a little to get the lubricant flowing to the right places. The WD-40 will also help clean this part of the carb. regular carb spray cleaners are way too strong and can damage the sensitive parts in these carbs. Don't use any and dont ever soak it in carb cleaner. Only spray clean it with non-flammable brake cleaner. Sounds funny but it works and won't hurt the delicate carb parts. Good luck because you may need to rebuild the thing even after it is cleaned.
