Eric,

I would think anywhere between 50 to 2000 quid, depending on variables too numerous to mention. If you narrow the scope of what you are looking for in reguards to condition, completeness; overhauled and road ready to incomplete basket of bits, you might get some responces. Otherwise I expect no one knows where to start short of writing an extensive reply to try and cover all the bases.

Regards,
Doug

 Hi Doug I knowwhat you mean,when I take this austin seven engine out all I shall have is a rolling chassis.so wil need every thing engine wise.and as I had my last original mk douglas back in 1959 and a ew in 1978, (ive run scotts ever since) I am afraid I have lost contact with douglas prices.my only concern is that I dont end up paying more for a box of bits than I could have bought a compleat engine for.as a retierd forman mechanic with machine shop experiance im not botherd about how much work I have to do.it stops me from going compleatly barmy.

 Hi lads can any of the MK experts tell me what parts you can use from a stationary engine on a mk engine. the reason I ask is that there seems to be a lot of stationary  engines for sale.have seen three today at a auto jumble. any thing from 25 /50.also a number of mk crankcases. is it worth buying one as a basis to builed a bike engine.or isnt it worth the trouble.

Eric,
       The only parts from the generator engine that will fit the motorcycle engine are:
      Barrels and pistons will fit the T35 Mk1 (but not later Mks)
      Cam gears and idler will fit Mk3 -5 machines, but need spacers to make width correct.
      Crankshaft can be used but needs slight modification at front end to accomodate drive gear for magneto.

  Regards,
                 Eddie.
