I can feel it losing power after 10-15 minutes. The problem becomes obvious if I put it on the slow idle and just park it. The engine eventually dies after very slowly losing the speed. It is Craftsman 9hp Tecumseh engine. Just before dying if I push primer, the engine gets reprieve until it starts dying again.
The obvious answer is "go clean the carburetor" but I am trying to find if there are any non-invasive "dump miracle chemical" in the tank procedures.
It had been working pretty well after I had removed the bowl nut and cleaned and squirted the carb from below before the start of the season. Of course, I only did that because it was not starting at that time! This particular problem of losing power after 10-15 minutes has plagued this blower for last couple of years and I thought I had nailed it but now it is back again. I suppose there are dirt or some disintegrating parts in the fuel system causing the problem.
Do I have any choice but to at least remove the bowl nut again and clean all the orifices on it? I don't really want to do it if it can be avoided but Gumout and/or Berryman has not helped. On the contrary I wonder if it is making it worse by causing more disintegration inside.
