    I am trying to identify an engine which my friend has described to me. He may be able at some stage to return to take a photograph.
    Here goes: horizontal single cyl. diesel, enclosed crank with ribs on the upper part of the crankcase , twin flywheels each with four circular holes, square cylinder head with central injector, Blackstone and Co. Ltd Stamford England cast into side of crankcase. Sorry that is not a lot to go on but if anyone can link that info to a picture we may get somewhere.

    Thanks Dan,
    I had googled Blackstone engines a couple of times but the site from your link had not appeared. I hadn't thought to lookat the online manuals but looking just now it could be a OP or JP. I will show him this and if we get any pictures I will post them.

    Looks like an interesting project. And still on the remains of an original Blackstone trolley...

    Regards

    Dan, thanks for the information about the trolley. I suppose I had better not cut it up! Had a chance whilst waiting for the tide today to soak bits of the engine in diesel . Took off the "air filter" I think the inlet valve gear will need some attention! I hope that the inlet valve was closed when the engine was left. It seems to me to be a design flaw if rain water can quite easily get to the inlet valve and collect there. The serial no. of this engine is: 199840 and it is rated at 18hp @500rpm.So this should help me to date it. Here are some more pics which I took today sitting on the quay at Portaferry.http://picasaweb.google.com/roadster541/Blackstone?feat=directlink I can't seem to display photos in a post, only to paste a link.

    I find this style of Blackstone curiously attractive ! And one day I shall own one. Hopefully ........

    I'd say with a number in the 199xxx range that it's about 1937.

    Spot on Dazla; it has been dated by Michael Key: October 1937. I have made a bit of physical progress whilst waiting for tides. The head came off quite easily, left the piston soaking for another day, took off the crankcase cover and split the big end bearing.
    This evening a couple of blows with a 14lb hammer and the piston moved!
