    Can anybody help please?

    I have a single cylinder air cooled engine that I cannot identify. There is a plate on the side that just has P. and Type AS. I attach a couple of pictures. I have given it to my son as a project, but it would help if we knew what we were working with and could then possibly look for manuals....



    Thanks in advance.

    Its a Petter A(S) not sure what the S is, its 1.5hp and is missing its top cowl to direct the air from the flywheel to the fins.

    Sorry Martin, It's a Petter AS and that makes it a ministry spec engine, missing the top cowl as you say and is 2.75BHP at 1800rpm.

    No problem, I was 95% accurate, I did say not sure of letter A and couldn't read spec plate.

    Nice project, I regret selling my A type, something a bit nicer about them than the later A1's etc. Good luck with the restoration !

    Thanks for all the help. I am struggling to find any information, workshop manual etc. Any suggestions where to look - the "AS" seems very rare or is it a variant of an "A" or something similar??

    The AS was an uprated version of the A so most parts are the same as the A, manual will be close enough for what you want. All parts are interchangeable between the A and AS apart from some carburettors, have you a photo of that?
    Tinwork will be the same.
