Brush Cutter fuel ratios

[yottie]

I have a wheeled (domestic) brush cutter which I haven't used for a long time.
Unfortunately I can't find the user manual.
Am I correct in assuming the fuel/oil ratio for the 51cc engine is 40:1
Many thanks

You can use 40:1 or 50:1 mix......these days, the likes of Oregon lubricants go for 50:1 to minimise pollution, and machines cope with this perfectly well.
For self mix I'd recommend using E5 petrol, or an Aspen type of fuel if the machine is stored for long periods.
