Thanks again all, I now know where I stand with regard to the disc boss and fitment of a B&S.
Thanks Bigted for that link, that's cheap as chips and I'm almost persuaded to test my patience. What's the 'average' life span of these Tecumseh 207cc?
Do B&S engine series numbers relate to ft.lbs of torque, ie: a 550 series has 5.5 ft.lbs?
