Re: salvageable Engine?
That piston and cylinder look pretty bad. Are the rigs broken? Does
the piston skirts front and rear have vertical scrape marks on them?
What about the cylinder, does it have aluminum from the piston skirt
or ring lands (between rings) imbedded or melted to it? If it does, just scrap it and buy a new piston and cylinder set. Plus you should look at the spark plug to see if there's little tiny particles of aluminum stuck to
the inner electrode.
