It will answer everything you want to know about the kit.
I found the link the other day when I was researching my build of the kit. I started about two weeks ago (I build real slow).
I have the rods painted and the pistons attached, filled and sanded. I have filled the hollows in the crankshaft counterweights with resin and am now filling air bubbles in them before I paint the crank.
Since I wanted to be able to build up the pistons to the rods before assembling the crank I have had to modify the sequence of construction.
The pistons won't fit through the spaces between the main bearings so I have to build up the crank throw by throw, putting the crank pieces up from the bottom and the rods and pistons down from the top.
I did a test fit this morning and it looks like it will work fine.
