I was about to close the bottom end of my engine and noticed that there was nothing holding the kick starter shaft in place. The knock pin had been pushed in and was flush with the case. I assumed that this pin had to stick out about 3mm to fit the slot at the end of the shaft. I had a shop remove the pin by welding a piece on the top. to my surprise, the pin measured 15mm - the same as the one I just ordered. Also, the hole the pin sits in runs straight through to the outside of the upper case. I do not understand how this could possibly be standard. Water will seep through into the bottom past the pin into the case of the engine. Is this how the engine was designed? Would I have to order an oversized pin? Any help would be greatly appreciated.
