    Simplicty Soveriegn 7100. I have what appears to be a power issue. When mower deck is engaged and going up hill the tractor boggs down.

    Simplicity Sovereign Lawn and Garden Tractor
    tractor Mfg.#1692943. It is a 1997 model
    The deck is a 48" cut and the model # is 1691219
    This tractor has been re-powered with a top of the line Kohler CH25S
    The engine spec# is 68544
    Disp 25?
    Serial Engine#2633815377

    I have it in the shop since November and stopped by last week was told that it might be a control unit. Because the engine was running on one cylinder. My question, is it worth the investment?
    My concern, Considering there may be more wrong with cylinder.
    $200 controller plus engine removal.

    Can't say? No hour meter. Came from another tractor before I ended up with the tractor. Looks heavily used.

    Check your compression. see the difference between both cylinders.

    If I find the compression different than how much $$ for a rebuild? Assuming it needs a rebuild?

    Would it be possible to do it myself? I need to decide if I it is worth the fix?

    If you never did a rebuilt. it’s asking a little to much just watch your torque settings. watch your ring to cylinder gaps. As far as rebuilt kits with gaskets they going to range from $200 to $250 depends where you buy. If you decide to rebuilt and need help feel free to ask.:drinkup:

    A few more questions.
    The rebuilt kits you mention, do they include cylinders/heads? Assume gaskets?
    What should I expect to pay someone to do this work? Labor? Parts?

    And the controller that was mentioned by my mechanic he says $200/part $600/Labor?

    With all this should I just throw in the towel or is there somewhere I can get a reasonible price on a engine?

    kohler recomends not to rebuild the comand engine and even if you did it would cost 600-800 for the parts alone. there are no kits to do this.
    my first question would be did you take it to a kohler dealer? one that has a master mechanic that went to the kohler school? there are leakdown tests that will tell you exactly what is wrong with that engine. and a tester to test coils and the sam (spark advance module) the controler that you speak of.IF that is the problem those things run about 75-85 dollars list price. now the labor is another story it will take 3 hours tops to just remove the engine. if that is how they will go about it.me i just pull the drive shaft off the front then pull the bolts from the shroud of the engine the tip the shroud forward./i can then get to the coils and the wireing to the sam. i still charge the flat rate as all shops will r & r(remove and replace) i think is 5.5 hr so yes the labor is high. then again its a simplicity and everthing is high.

    and joe keep on drinking bud lol!

    Is there anyone interested from Western PA to take on such a project? or where can I find an engine that will work. Horizontal shaft (rear of engine) and exhaust in front.
