I got the Cub Cadet 782 out to blow snow last night. It ran good for about 5 to 7 minutes and then lost all rpm. It would still idle. When I shut the blower off, the engine speed did not increase noticably. I limped it back to the garage. I took off the air cleaner housing, thinking it might be plugged. That did not help. A little while later it picked up speed. I took it out and the scenario repeated itself. I played with the governor linkage moving it by hand, but that did not make much difference. Is it possible that I have a slug of ice in the fuel system and the fuel flow is too slow to give full rpm? This is unleaded regular without ethanol. Usually I have the garage warmed up before trying to use it in the winter. Thinking about getting a little isopropyl to put in it tonight. First time used this winter for blowing. Any other ideas?

It makes ethaonol fuel look better. Yes fuel line antifreeze is alchol, adding it will help once it is warm enough to melt the existing ice. Jim
each early winter i add fuel antifreeze to all of my vehicles and machines--gas and diesel--they all always accumulate water do to condensation throughout the year
I was pushing snow one day in 10 degree weather, after about 2 hours of pushing i had to back up a hill, that made any water in the diesel fuel tank go to the fuel line outlet and it froze solid! after about 2 hours of thawing with a torch and then bleeding the system i got it going again

in the last couple years, I've had multiple problems with shelf life of unlead reg without ethanol, that I kept around for small engines.
I now only buy premium gas for small engines as it seems the shelf life is excellent. the most obvious is chainsaw gas where I couldn't get a jug to not go sour in as little as 3months. now with premium it lasts well over a year!

I have an Allis Chalmers C that would do the same thing, I figured out that it was icing up in the venturi on the carb. gas line deicer helped but didn't cure the problem completly, you need to run some warm air through the intake. I ran a hose from the intake to just above the exhaust manifold and that solved it for me.
As I said in the original post, this is regular without ethanol. I too have used gasohol or E10 or super unleaded or whatever they want to call it next since it became available. The only trouble that I ever had was in a 1970 Chevelle that plugged the very small OEM fuel filter in 1980. I am not one that badmouths it. I haven"t had any gas line freeze in decades. However I do not use it in small engines, especially 30+ year old ones.
I have almost no fuel related problems other than other people leaving gas in small engines that I acquire to rot the carburetor.
I will get some gas antifreeze and warm the engine and gas to around 50 degrees Saturday to see if things got better.
Thanks for the replies.

Carb ice. Did you take a look inside the carb after you removed the air cleaner?

I live in the garden state (new jersey) and i found out premium gas by law can have NO alcohol in it, thus we use premium in all saws, splitters, and anything that sits. Also from a 50 year mechanic, shut gas supply and run engines out of gas. Merry!
Friday I put an ounce or 2 of isopropyl in the tank. I had the garage up to about 50 degrees and started it up. I let it sit outside with the temperature only up to the mid 20's. I fired it up Sunday and ran it about 20 minutes and it ran fine. Hopefully it will continue.
Thanks for the help.
