I am new to this site...


I have yellow P-38 with 2 Ralph Cunningham modified engines. Before the magnetic pick-up wiring broke both engines ran great. Now I need to get into the front of the engine to replace the pick-up. I have NO IDEA on how to remove the prop drive off the engine. There is a place to put a wrench on the crank shaft, however there is no resistance when I turn it. There has to be someway of stopping the movement of the crank to loosen the drive. Are there any engine gurus out there that have any idea how to take off this drive assembly... I am waiting with baited breath for an answer.. I have attached a pic of said engine.

Please call me at 707-3658878 (cell) if you can help me.. My name is Monty THANX
