Location: Elk River, Minnesota | Hi Everyone,
I'd take the shock treatment a step further... Mercury powertune or a seafoam equivalent sprayed directly into the carbs while the engine is running High idle... spray and spray until the engine finally wants to die (lots of white smoke)...let the motor die, and spray another 4 seconds into each carb. Let the motor sit for about 25 minutes, then take her out and run it open for a while to burn all the gunk out. That should clean the cylinders and the cylinder walls, along with some gunk on the plugs (if there is any build-up). After the procedure, the motor should run smoother at all RPM levels...
Also, with the bulb...that makes sense too...so before going out and buying a new one, if you have a separate tank with a different hose, try that first....if it runs well, you've found your problem.
