The Key that connects the Impeller
I can't find the woodruff key hole for the key, there's a slot for a wrench but no slot. I'm going to try and put back together and check all the vitals, spark, compression, fuel... is this the fuel pump in the photo?

There is no hole. The Key in this case, fills the Void in the Driveshaft

Remove the 2 narrow covers above the fuel pump in the picture.----Allows you to look at pistons / rings.
