Have you not got ISO BU 416A, there is a clear drawing showing how to install them.

Unfortunately not although I am building a 4" burrell single I started well before the Steam traction kits so many of my parts have been machined by myself, but as they are the exact same model both this has both enabled me to buy some parts or look at the models first hand taking measurements to help me build mine using similar techniques so technically as an interloper. I am now on to assembling the motion and although I have a drawing showing how they should sit I wondered if the instructions sent out with the kit engines gave any more details to enable a better setting up for the timing ect.

Oh I see.
On the STW kits there is a keyway already milled in the crankshaft and the eccentrics have keyway milled in them, so they will only fit in a certain position, not adjustable.

Thank you I will have to go as close as I can the same as the drawing and make adjustments if required
