Hi My Dad died and I have inherited his Toro TX159 GTS. It wouldn't start at first but I cleaned the carb and it fired and I thought jobs a goodun but after a few minutes it died. So I cleaned the carb again but still it died after a few minutes. If I leave it for a minute it fires up again but lasts only a little while and then dies. It's like it gets too hot or something. I thought maybe that the petrol cap was too tight and wouldn't allow the fuel to drop down so I loosened it right off but that also failed and it wold die. I've cleaned the carb half a dozen times now but with no success. Anyone with any ideas. The air filters mint.
