Though you may be ok (I’ve did it many times in the past), I would say run a fuel stabilizer, I really prefer seafoam, that should keep your gas from going bad, and possibably varnishing up the jets in the carb, which could cause you to run lean and burn a cylinder. Lots of products out there stabil, star-tron of course my favorite seafoam. Cheap insurance IMHO, plus seafoam and star-tron both reduce carbon build up which is also very harmful to rings and motors. Stabil just stabilizes the gas, and too much stabil can cause problems (if you can properly read directions that’s a nonissue). Star-tron is new, personally I haven’t used it yet, but people seem to like it thus far. With today’s Gas ethanol or not, it’s appears to breakdown faster and IMHO it’s cheap insurance to prevent this from happening.
