    One other thing not mentioned directly is to keep the cooling fins clean. Another is fix little things, especially oil leaks, immediately before they cause bigger problems.

    I've had them drug into the shop with no fuel no oil and no filter and nearly anything under the sun stuffed in the filter box, All complaints of not starting...... Just when I think I've seen it all another pulls in.

    A foam rubber air filter (piece of mattress) is better than a hand full of tree moss stuffed in a filter box......

    This came in last summer, Was less than six months old;

    Although it never ran with this in it......It must have ran with nothing, Engines won't run without compression...... :hammerhead:


    Proper maintenance and preventive maintenance along with proper parts is the key to engine/equipment longevity......Plain and simple.......

    I agree most of them go bad due to maintenance issues.

    That said you can't expect a $200 briggs to last forever. They come with aluminum bores, plain bearings, plastic cams and what not. Even so it's possible to stretch 500-1000 hours if taken well care of.

    Personally I'm a tad disappointed with ZTR engines as most get tired at 2000 hrs and these should have far better components than home-owner versions.

    ZTR engines are run under a lot more stress. It takes a lot to get all that steel on your deck up to speed and most people engage the deck at full throttle. It also take a lot to move these heavy machines around, how many times to you stop, turn around and go again on a single lawn.
