Lucid, in one of your posts you mention the service socket on the 240, with a picture. Do you know if the 740 has this? I get a hot no start no crank on occasion, when it is very hot and humid out. It does start when I use a screwdriver on the starter terminals. I know I could rig up a button but would rather not. I'm suspecting the ignition switch, as I've already cleaned up the neutral safety switch and wiggling the shifter doesn't help.
