Hi
#1 Holder for something?
#2 Is this it for oil lubrication for the camshaft?
#3 Is it stud or bolts to attached the camshaft?

In the scond picture, should it be some lock washer?

Does anyone have some pictures? (or exploded view over the motor)
thanks,

I didn't rebuild my motor but maybe this picture will help with item #2

Hi
thanks, yes, looks like a lock washer for camshaft nut and a coppar pipe for lubrication (I have a thread in the motor block..)

Here is another picture:
