Starting up the old Bedford SB3 Bus after 2 months of sitting 

She's a petrol

Some Bedfords were powered by the 400 Leyland ( in Australia at least ), but most were the 330, 466 and 500 cu in diesels. The petrols were the 214 and 300 cu in engines. I think from memory, the Leyland made 120HP and the 500 made about 140HP.
