Devoisi,
The three piece / solid deck, looks much sturdier than the one piece / split rail engine mount frame I have..

Where the engine sits on my split rails it looks like they (the rails)"sag" a little. Will this be a problem for proper engine / clutch shaft alignment?

I noticed another forum members' machine looked to have had a similar issue, Stu45 from memory..

Also, my machine has all the details as Deejay has explained to match a "Mark 2" though has horizontal chain case cover screws..?
