Well, I couldn't get my fat fingers in far enough to clean the contact point on the boot, so I went down to the local ped shop and got a new boot. Sits real pretty and gets lots of juice. However, still can't see it sparking. Checked the (new) plug using the lawnmower and it definitely can spark. I think part of the problem is just getting some of the idleness out of it. I was peddling like crazy yesterday and the lights came on for the first time since I've had it. Any other ideas on the spark issue? I don't know what else it needs to spark.
