Buy decent oil and ignore the 16:1 breakin instructions .
well, heres the thing, i took the head off and spark plug out durring the break in just to see if it was doing that, and it wasnt. it was just a dark stain with metal underneath it and you could tell it wasnt something you could scrape off. but this third tank of gas with the change in oil has it now all gummed up. i took a flat blade screw driver and scraped some off. its like nasty hard goo that burnt on in/around the cylinder, piston , and spark plug.
every run is a test run . . . and i just hope it dont blow up - wil
