I've looked at the price of their engines. That engine is $170 plus shipping. I don't know what kind of attitude your landlord has towards money, but $170 is hardly something I would call "cheap". But I will say this. IF you are able to rebuild the engine and install the replacement parts CORRECTLY, it may well be worth it to fix. But if you aren't able to repair the engine (and not knocking you, plenty of people including myself dont possess that type of know-how), then it may actually be more economical to replace the engine than to spend and possibly waste money attempting to repair it. I used to be a two stroke guy and wasted money on a cylinder rebuild kit, not knowing at the time that my crank bearings were also shot. I would hate to see someone else go through something similar.
