Since the parts are used, It is very important for me to make sure that your aware of any imperfections. All parts on the ad, are mechanically in good working condition unless its described, clearly seen or noted in the pictures. Cant Guarantee if piston rings seals or gaskets are in working condition, Unless its noted otherwise in the pictures. All parts are dirty and need to be cleaned. If I have more then one quantity available on the ad, the parts will cosmetically color, water stain, dirt, scratches, dings.. Etc differ from each other, but mechanically they will work. I will send the best looking first. I will be using whatever is cheaper. First class is 2-5 day……. Please do your own research.. Usually everyone shops by a part #. Most of my parts that are posted with a part# and a name of the part.. The way you would find that, is find a model#/name of motor then Google it. Google should give you websites that should have schematics… Then let me know what your looking for.
