Good one Bob, and for $690. Aus you can get a kit that comes with a new crankshaft , take the $200 odd that it takes to have the old one ground and it looks attractive . One thing to keep in mind is that there are two versions of the Standard petrol engine ; the TEA and the TED . The TED was designed to run on Kerosene and has a vastly different head . Engine block and general lower end is all the same though . Serial number and model designation is on an alloy plate on the steering turret Tony .
