OutdoorKing Repair Forum Forums Repairs and Maintenance Questions On Hand Held Blowers/Vacuums Petrol Blowers & Vac's 25:1 or 50:1 for my Shindaiwa EB3410 blower?

Thanks everyone. One more thing is that the mechanic said to use 91RON with 10% ethanol as the 95RON & 98RON have additives in it which are bad for something or other? Perhaps the engine or carby?
