Thanks Dylan
I've got a copy, although not a nice coloured version like yours.
I've not given up yet, I feel I must get it going again if only to justify everyones efforts on the forum!

I bought my Diesel Engine compression gauge back up with me just in case you were still struggling.
Its a Sykes Pickasant one - but looks a bit like this: http://www.thetoolboxshop.com/43053...it-4364.html?gclid=CO_Q0oz_w7gCFY7LtAodAlMA1w
Let me know if you want to borrow it and we could arrange something. It will give you a reasonably accurate reading of what compression is actually being achieved. If the compression pressure is fine, then provided the valves open and shut at the right time, there's no blockages of air inlet or exhaust, and it gets a squirt of fuel through the injector at the right time then it WILL go. If none of the adapters fit then we will have to arrange something (like I will get an adapter machined! but with me away for a few weeks that won't be ideal.)
We can easily call into Holy Loch as we head down the Clyde as we set out on our summer cruise on Sunday or Monday if that is the simplest.

John,
That is incredibly kind of you - will get the injector back on Fri. and hopefully that solves the problem.
I will keep in touch.

Now thinking ahead about possible replacements should the engine be in terminal decline.
Yanmar 1GM10 seems a popular repalcement on my type of boat - although the propellor appears to rotate in the opposite direction from the MD1.
Does anyone know where I could find dimensions of the Volvo 2001 (9.5hp)?

This spring is purely a friction device to hold the decompressor in the decompressed position. WHen running it has no use as the weight of the knob keeps things in the right position. In the OP's engine 50% of the plate spring is missing and is probably sitting in the push rod chamber from where it can be retrieved.

Lets find out what is wrong with your engine first. Why spend thousands when you might be back in business for the cost of an injector nozzle or head gasket.
I know of someone with similar mindset who replaced an MD2B with a Beta and then found the Beta wouldn t run either. The fault was in the fuel system

Just found this on a search as a friend is considering buying a westerly with a similar engine. Did the md1 ever run again? Please Gavin put me out of my misery. I like happy endings on engine threads - not like some!

Hi there.
The MD1 does not live!
It needs quite a substantial injection of capital to restore it to full working order.
However, the problem was not caused by mechanical failure but by water ingress (we think) via the exhaust system (poor seal at a gasket allowing water to enter the cylinder head).
If the repairs were carried out then the engine would probably be good for many more years (it never missed a beat in the 10 years that I had it, and the engine was manufactured in 1967 - so pretty good going!).
When I bought the boat, I was wary of an old engine and had thoughts of installing a new one - but in fact, the engine was perfect and would still be going strong were it not for the above fault.
We are replacing the dead engine with another MD1 as its a straight swap.
I wouldn't be put off buying a boat with an old engine (but would get it checked by an engineer, not the surveyor) - after all, most terminal faults seem to be caused by ancillary components and this could happen to a new engine just as easily as a 45 year old plodder!
