OK, I guess I wasn't all that scientific about it. I used a screw in for the first one...but it got stuck, wouldn't unscrew as the tube just spun in the screw end.
After getting that out we used a push in rubber ended one...so the numbers are 'close' since it wouldn't set a pin like the screw in one.
Also, I was turning the engine over without the ignigion coil hooked up. I though this was done just by cranking the engine using the starter...is that not correct?
