Why is there excessive black smoke in the exhaust of my Toro 25430?
Excessive black smoke in the exhaust could be due to several reasons. If the engine is under an excessive load, reduce the ground speed of the machine. Dirty air cleaning system elements may also be the cause, so service them. Additionally, improper fuel in the fuel system can lead to black smoke, so drain and flush the system, then add fresh fuel.
What to do if Toro 25430 engine starts but does not keep running?
If the engine starts but doesn't keep running, check the fuel tank vent for restrictions by loosening the cap. If it runs with the cap loosened, replace the cap. Also, dirt or water in the fuel system could be the cause; in this case, drain and flush the system, then add fresh fuel. A clogged fuel filter or air in the fuel can also cause this issue, so replace the filter and bleed the nozzles, checking for air leaks.
