Engine surging after warmup

Had our first significant snow this weekend. Took the 1984 Toro 7/24 out to blow the drive and walk. Tempature was about 3 below. After about 25-30 minutes of blowing the engine started to surge. Checked gas, and there was plenty (1/5 full) in the tank to rule out gas stravation as the cause. I was able to finish the job but the surging would occur periodically, then back to normal. Any ideas as to what else may be the problem? Thanks for the help!

my neighbor experienced a similar problem on a generator in cold weather, ( ran it full time for a 17 day power outage a couple of years ago) which i suspect is due to moisture forming in the fuel system and condensing in cold temps. his has no neat shield around the carb (where mine does so i think the carb stayed warmer helping elimate the problem on mine. ) & after it had run long enough to get good and warm would surge so bad under load it would almost die to anyway to the point.....what we found did alot to solve the surging problem was add a litle heet fuel treatment to the gas, it helps displace moisture & prevent ice from forming. another case during the same storm someone told me about and indicates its a condensation problem ......same thing, after a while in the cold his generator started surging badly......he rigged a cardboard box around the carb/air intake to help heat the air and carb.....and the problem went away. perhaps try both....some heet and some sort of heat shield around the carb to hold the heat in during very cold temps
