    I just bought a 2001 Lazer with a Liquid Cooled 27hp Kawasaki, I got it for next to nothing and I know it will need an engine. My question is will it be cheaper to get it rebuilt or pay 1500-1800 for a new engine. If replacement is the best bet, where is the most reasonable place to buy an engine.

    Right now the mower has a ticking noise, does anybody know what may fix the problem to avoid replacement.

    A ticking noise sounds like possibly the rockers out of adjustment (Valves).
    You may want to check the valve adjustment and see if that takes care of the ticking.

    I'd just rebuild the heads and leave the bottom end alone provided

    I woudl do the valve adjust on all valves like rob mentioned. then Id consider doing the heads...but I would not touch the bottom end unless youa re sure that where the noise is coming form..

    Restorob, Obviously you have the shop time invested to have seen the engine failures. 25 to 30 years ago, everything was powered by a Briggs or a Techumseh, larger machines used a Kohler or a Wisconsin, Onan was a popular generator or Gravely engine. I have been out of the pony engine wrenching business for 25 years but still get asked the question, who makes the most durable small engine? What is your opinion?

    Accurate,
    Every one of the Robin engines have dual bearing crank supports. The sound like a sewing machine (smooth and quiet running) and seem to last for ever. They build engines from like 1.5 to 25 hp engines. They need to start building some 30 to 35 hp engines though. The Generac engines seem to be pretty close to the Robin and they do have V-twins up to 38 hp I believe. Just my opionion.

    Thanks guys for the info, I will check the valves soon as it warms a bit. It may just be something that small, would be great.

    Well I went out today to take a look at the machine to find the noise by the engine. This was the first time I went to look at it since it was picked up and you will not believe what I found.

    I took a rubber hose to follow the noise and make sure it was coming from the top half as indicated above. And the only thing I found was a metal plate between the engine and seat (like a heat shield) that was ticking. I attached a metal screw to hold the plate in place and the noise was gone.

    The guy I bought it from swore the engine was going to need to be replaced, so he gave me this 2001 Lazer Z LC 27HP 60" for a woping $2000.00. I guess now I will give it a new paint job before spring and enjoy the good deal.

    Thanks for the suggestions, the problem is fixed.
