    Why do the lawnmower engines seem to always need a re build or swap. What is causing this. Neglect ?

    Well most common issues are the "Ride it hard and put it away wet" mentallity many use with their equipment. Im meticulous about oil changes, checking valves, fuel stabilizer, etc. Many people are too lazy and see a new motor as a cheaper and easier way to deal with motor issues.
    Top End rebuilds(Piston, rings, honing cylinder walls, head work) and Low End rebuild(Cranks, Rods, other bearings) are a part of a motors life and are needed after extended engine life. Basic maintanece is key, and will keep a motor going longer than most expect.

    The problem is twofold...
    Neglect is the big problem...
    Some guys buy a mower knowing it has a warranty and proceed to beat it like a rented mule..
    They oil that comes with the engine doesnt last forever..neither do the filters...

    The other bid problem...To Quote BigFish..Is you cant fix stupid...

    Stupid mechanics that cant fix your engine...but can install a new one..
    Stupid eqpt owners that believe everything they hear at the mower shop...

    Read the manual. I'm willing to bet that fewer than 1 person in 10 reads the owner's manual.

    If everyone read their owner's manual our parts and service business would suffer. Fortunately, for us, they don't.

    Let's examine the fact many small engines contain no fuel or oil filter and a piece of foam rubber for an air filter.
