Small engine help

Discussion in 'Home Repair' started by Sacramento Dave, Mar 25, 2006.

  1. 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?

    Start with a good external cleaning of everything that moves,
    especially the linkage. Look for things rubbing, sticky, etc..
    WD40 is good for cleaning. Air hose helps some too.

    Check the governor linkage. That is the flapper under the cowl and the
    skinny spring to the carb. There may also be an adjusting screw.

    check your air filter..sometimes when they get dirty they will do that.
    Is it a briggs and stratton engine with the carb mounted to the fuel tank???
    If it is sometimes the carb base will warp and it will suck air between the
    carb and the tank and get the same effect.

    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.

  6. I'm not familiar with "Sea Foam". What is it and where can it be obtained?

    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.
