After some consideration and skinning of knuckles etc the engine went back in and after circa 10 hours we gave up for the day and Tear'y
@Tirran put it all back together, radiators etc, front poanel, everything and on Monday lunch timeI went round for the grand starting.
It started first turn.
But wouldn't go into gear and when it was in gear the clutch was dragging.
"Oh bugger" said
@Tirran , I wasn't really listening as I was hunched in the corner crying.
It turns out there is a right way and a wrong way to install the clutch plate ... who knew ?
Anyways ... 6 hours later we'd taken the front off, emptied the water, disconnected the exhaust, fuel, oil, electrics and air got the engine out (again) turned the clutch plate around, put the engine back in (again), connected the electrics, air, oil, water, fuel, exhaust and .... this time (again) it started 1st go and now we can get gears and have a working clutch.
Hopefully TT doesn't have a leaking rear crankcase gasket ....
If he does, i'll be hunched in the corner crying again.
