the engine on my lawn edger has started pulsating. the RPM's go high and
low. It has been sitting for awhile, but I do put gas saver in my gas before
winter. The edger is about a year old, If I hold the throttle linkage it
runs smooth, the linkage move when running. Any suggestions?
I would look for some sort of air leak, a loose screw or two (on the
edger, not you). I doubt if it was the gas, but it is possible that it has
gummed something up inside. If so since you can get it running, it should
clear out after a few more uses. Next year try to let it run dry after the
last use and dump the old gas in the your car's tank (unless it is a
diesel.) Even if you normally mix oil in it, it will not hurt the car.
Well you have gotten several good suggestions. If nothing is apparent right
off, I would put some SeaFoam or similar product in the gasoline per
instructions. You may have developed a little varnish, moisture or other
contaminant in the carb over the winter. Sounds like it is lean.
SeaFoam is the latest rage of gasoline additives similar to "Gumout" for
cutting carburator deposits, carbon in combustion chamber, pick up moisture
from fuel, etc. I have little experience with it but several on a small
engines list I monitor have good things to say about it. Our local Farm
Supply Store has it, I would expect most Auto Parts Stores and perhaps,
Wal-Mart. $5 - $6 per can.
