I'm starting a road trip on Saturday and wanted to check the timing on my 245. It seems to me that the acceleration is a bit sluggish. Anyway, I got out a timing light after checking the manual so I could see if the timing was set at 12 degrees BTDC for cylinder #1. Facing the flywheel pulley, I saw that the timing was set to the mark farthest to the right. I tried to loosen the bolt holding the distributor so that I could turn it, but it was very tight. I put some force into it...Then it popped loose. However, I could not turn the body of the distributor more than about 1/8th of an inch. the bolt was loose, but the distributor seems to be stuck, and the clamp bolt won't tighten, it turns uselessly. I'm confused as to what is going on. Did I break the bolt off above the place where it clamps the distributor in place?
