Does anyone have the specifications for the oil inlet valve spring for early 2 3/4 engines - Part number 424.   I have tried to order one from the club spares but apparently Jeff Swan is indisposed at the moment.

Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

 Hasnt any one got an idea of the value of a post war engine.

ERIC BAYLISS

being as no one apears to know the value of a post war engine, has any one got one they dont need, or are they difficult to get. as I would like to put this mongrel austin seven engined bike back as a proper douglas.thanks

Doug

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.

ERIC BAYLISS

 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 BAYLISS

 Hasnt any one ever stripped a syationary engine to see what bits you can use on a mk.

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.

 Thanks  Eddie wish I had bought one of those on saturday, the one crankcase was marked t35 as well.and was only £25 including cams.
