    I have just acquired an engine at the opposite end of the size range which usually interests me. The previous owner bought it for the gearbox; a Hurth. The unusual feature is the position of the injectors they point fore and aft. When I first saw it I thought that it may be Italian as it is all, except the cylinders, aluminium. On closer inspection the threads are unified it has a Lucas starter motor and oil pressure switch and an English AC fuel filter. It had been partially dismantled before I got hold of it. The bottom end is seized but there is very little wear in the bores which are 3". Can anyone identify it? If not we maybe able to x-ref the piston number. There are some casting numbers but no makers name at all. There are rivets in the flywheel housing which look as though they may have secured a makers plate. This engine is water cooled but the top of the flywheel housing looks to have a duct for an alternative air cooled version.

    Hi. That's a Petter AC2W, dating from the 70s/early 80s period.
    There are plenty of them still about, so you shouldn't have too much of a problem finding bits for your unit.
    Have a look on the link below, and scroll down to the 5th photo/diagram, and you'll see your model of engine.

    They crop up regularly on Ebay (in varying states of repair), such as this one below.

    Hope this helps. :)
