Some of you might remember from last winter -- I lent a friend my little Husqvarna 142, and he burned out the piston. Accidentally straight gassed it. Its not cost effective to have my local dealer fix it (parts and labor = same as new saw), but I can get the piston and cylinder for about $80 from Baileys. While small engine repair is not my specialty, Im no dummy either, and am pretty sure I can tackle this project. How much of a nightmare is this job?
