RE: SYSSA 30CC GAS MADE IN USA
Could be. I know there is a lot of variation in gas here due to all the different brands, ethanol, etc. Also, some of the gas stations don't have a great filter at the pump.
I have over 500 hours on my engine now and have cleaned the carb filter four times, usually after the engine starts getting flaky. I think I will go to a 50 hour cleaning to prevent problems. I also have filters in line with filters in line with filters, etc. and junk still gets past them all.
