It should be fine.
These engines were produced around the same time in England when petrol was becoming more heavily taxed, which led to the creation of tractor vapourising oil, or "power kerosene" as we knew it. I have run a Ferguson 20 series on homemade "power kerosene" of 50-50 diesel and petrol and it ran without any problems.
Be aware though that in order for the Diesel to vaporise correctly the engine needs to be hot. TVO that was up to 80% diesel had trouble working in a petrol engine unless the tractor was ploughing or pulling hard.
