Bruce,How old are these things? Besides bad gas, the diaphragm in the carb can harden with age and cause this sort of problem.
My leaf blower needs a new one just about every other year. On the other hand, my gas trimmer (both almost 11 year old Homelite's) has never had a problem (it still has the original spark plug, I pulled it this year just to look and it still looks like new so I just put it back in). My parent's also have a Toro snow blower (also 2 stroke) that has the same problem as my leaf blower.
Back when I was cutting grass in my youth, I ran into this problem every now and then and a carburetor kit took care of it. Also, if your lawn mower has a plastic carburetor, it may be warped and need to be replaced. One of the mowers I had with stuck with one of those and the mixture screw assembly popped out if it frequently and it rarely ran good. On that one, I was able to replace it with a metal carb I picked up used and I never had a problem with it again.
Besides using Sta-Bil (or similar) additives, some 2 stroke oils contain a fuel stabilizer. I use those types in my chain saw and I haven't had a problem with it since I started using them.
Matt On 11/25/2009 5:20 PM, Bruce Griffis spouted this sage advice:
Must be the gas. I finally got the leaf blower running, but it would not go full out, just an irritating slow idle. It would have been quicker to use a rake. The lawn mower would go for about a second, then just stall. The mulcher just sat there. I pulled and cleaned plugs. So - time to drain and use fresh gas. Or have a Black and Tan. They're pretty good! _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
