The blower is about 5 years old and was running like a top until this winter. It would run perfectly for a half hour or so then stall out. The wife told me that she had solved the problem by simply topping up the gas. I thought she was nuts, but that's exactly what it's doing. I thought perhaps the gas cap might not have been allowing air in to tank as the gas was used but when it started stalling I loosened the cap and it did not help.
So in a nutshell if I top up the tank it will run perfectly for about one inch of fuel then stall. If I top it up, it's good for another inch. and so on! (I was thinking that I could simply move the tank up about the height of the tank and my problems would be over) But I am more interested in finding out what you think might be going on here.
Any thoughts would be appreciated.
