Engine surging after warmup
Original Message   Jan 23, 2005 12:11 pm
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!

spottedpony is right. Thats why I mentioned to clean your carb cause you could have watter buildup.

Thanks Terminator, I'll check into that.

SpottedPony, is that "Heet" additive like dry gas?  I didn't  notice anything in the owners manual that says not to use additives like that, so I'll give it a try.  I'll try to find some online and order it.  As for making a shield for under the carb box, I like that idea but I'm also concerned about starving the engine of fresh air.  I'm going to stop my my dealer tomorrow and pose these questions to him.

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.
