The shift linkage disconnect is behind the electric starter. Take the starter off and you will see it. When you reassemble it make sure the washer goes back on the shift shaft.
They are not wonderful if the repairs cost to much to actually fix them.
Kinda funny though one of the best engine manufacturers in the world still running 2 strks. Putting the engine under the water line is nothing new.
What is the serial and model #? That will determine what emblems or decals it would need. Also if it is a Wizard, Sears,Elgin or Scott, Mcculloch. These are 64 an seem later Emblems...
I am not ripping on you. With the price of your EMM and the parts you just bought you exceeded the value of the motor. That is just a fact. Don't be mad because your motor went obsolete in less than 5 yrs of being manufactured. Your mechanic should be able to tell you which pump. Why don't you...
The $185 one is a Chinese knockoff. The $500 is the OEM one and the one I would purchase. Or you can convert it to a premix motor with a $100 pump. As far as the prop goes look on the hub for either the size or parts #.
So instead of having it scanned and getting the specific code, you decided to load the parts cannon. Good luck with that approach. If your mechanic worked on it why did he not tell you why part was throwing the code. Everything you just bought probably exceeded the value of the motor.
Do not buy the cheap Chinese one off of eBay unless you plan on using it as a pre mix pump. Ditto with the used one. The no oil flow sensor is in the pump, so if the pump is still moving o there will be no alarm.
