When I purchased my used STC48V-26BS ( http://www.lawnmowerforum.com/showthread.php/39567-Help-w-used-Tiger-Cat-evaluation ) I had hoping for a long(er) run without issues. Reading through this Forum of all Scag issues, I am happy that my mower's trouble is not as complicated (and expensive) as are some.
Currently, the mower loses power, gradually over three or four minutes, with loss of velocity, loss of engine rpm's, and the end result is engine shut down for no apparent reason. If I turn off the PTO, rpms return to normal, but only for the time the PTO is off. With PTO ON, rpms die off over a few minutes and the engine shuts down.
Three weeks ago with the same symptoms, I took down the carburetor, cleaned the bowl and jets, changed the fuel filters, and added "Fuel Medic" to eliminate any water in the ethanol-laden fuel tank. I have not depleted that tank as yet. Everything seemed fine for the next two uses.
It has been raining, but the Fuel Medic should still be "working". There has been no added ethanol based fuel. The filters look free of debris.
Tomorrow I am going to revisit the carburetor, take it down, clean it again, see if there is any debris in there, and try again. Anybody have a suggestion other than the carb?
