[QUOTE="MrGiggles, post: 481977, member: 22613"] Leave the ignition key on, and rig up a short jumper wire on the starter solenoid, which is conveniently located under the cowl, to crank without using the ignition. An adjustable gap tester is needed to measure ignition performance. Just having spark at the plug is not enough, since the resistance of air goes up when it is compressed and heated, could have good spark out of the cylinder and nothing under compression. [/QUOTE]
