So, after very carefully checking everything before the engine went in, I had to lift it out once more the put the cross tube in first. That all went in quite nice until I checked the clutch and found the rod setup I made hit the cross tube funnel by a whisker so out it all came again
A bit of grinding and back in it went and that was for the final time. I just do not understand why on earth everything had to be made with very little clearance. These would have been dreadful to work on in the field.
