Can someone that has worked on one of theses help me.<br />I have a 1991 4.3 omc cobra.Have many hours of testing and asking question I have determined my ignition sensor is bad.It starts fine runs good till let it sit awhile then won't start.Crank and crank then all the sudden will start. We have determined that it loses the coil in sensor to find number one cylinder on start up.So I bought a new sensor.I have 2 manuals on this thing and it just says re install it.My question is how do you adjust it,it will slide up and down on bolts.I sure don't want the disk hitting the sensor as it passes thru them.Beings the sensor is mounted on bellhousing you have to nearly stand on your head to get to it.Anyone with any ideas?
