Morning Justina

there should be a spot on the front of the engine

Customer: replied 1 year ago.

Found it. Now the issue is....

~ on the old engine there is a shaft that comes out so the new engine must be electronic. Is there a shaft kit we can put on the new engine or do we have to put on an entirely new shaft?

~ which wires/posts on the alternator are for the electronic tachometer?

Expert:  Wayne replied 1 year ago.

alternator terminal for Tach, is either "W" or "R"
