Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

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!

RonnieRay - Richen up the high speed carb mixture screw (or power screw as Toro refers it) about a 1/4 turn counterclockwise. Surging is caused by a lack of fuel. This adjustment should cure it. If not, drop the carb bowl, clean the bowl nut, bowl & high speed needle.
