Then do you have an interfering partner (like me) who smugly reads it and tells you what you doing wrong?
Is it this one?
Specification for HUSQVARNA R153SV 21" / 53cm Self-Propelled Lawn Mower Briggs & Stratton Petrol
Engine Make Briggs & Stratton
FUEL TYPE Petrol (unleaded)
Looks like might get away with if engine run only short period on a hot summer day like today, even better if at altitude, and fuel drained and replaced and run engine at least 2min or so when discovered
think it indicates to use E85, the casting is of a fuel pump and delivery hose…
on the other hand… it might just mean leaded gas and not E85
perhaps add some of the stuff you can get for old cars…
I agree the casting is of a fuel pump and delivery hose. But I would interpret that as DON’T use E85. So it is a crap bit of signage!!
Our mower has a Briggs and Stratton engine and we use normal petrol, as I have for all the Briggs and Stratton powered mowers I’ve had for the last 40 plus years. But this one it is very old. So no idea whether the new things have changed.
