Older Tecumseh 4.5 Horse Snowblower

The house my wife and I recently moved into came with an older 4.5 or 5 horsepower Tecumseh snowblower (I can get the model #). I tried it out for the first time last night as we've been getting dumped on. It had about 1/4 tank of gas left in it from last season and I'm sure this is where my problem is but I added some new gas to it, it ran great for about the 1st 1/2 hour and then as I continued it would run for about 5 minutes then die, I would let it sit for a few minutes then it would start back up and run for a few more minutes then die again. I did notice that when I turned the choke on while it was about to die, it would fire up then finally quit. It did this 4 or 5 times until it got dark and I quit. I've been told that it may have something to do with condensation in the tank from last season, or the gas was dirty causing the carb to malfunciton. Any ideas?

There a couple of things to check for, I believe what is happening is your float bowl is filling up too slowly and will not remain full ,henceyour running out of fuel after 5 minutes. First off, do you have any type of restriction in the fuel line and/or is your fuel shut off turned off or plugged? (if you have one on that machine) Second , possibly your float is not pivoting properly and not allowing the bowl to fill up quick enough.
What I would do on something like this is a complete carb cleaning and also replace all the fuel line and if it has one, the fuel shut off.
You can go to this site and d/l a copy of the 4 cycle manual for your reference. http://www.cpdonline.com/692509.pdf
Let me know how you do.
