I have been restoring a 1985 Honda ATC250ES Big Red. I purchased it from craigslist for $200. It did not run. The kid that sold it to me said it didn't have spark. I thought that this would be an easy thing to diagnose, I was wrong. It took me a little over a year and $600 dollars to get it running. Long story short I replaced everything from the stator to the sparkplug and it ended up being the pulse generator. I had put a new pulse generator in but the gentlemen at the Honda shop told me it was no good. He put the old one back in and we had SPARK!!!!! I cleaned out the carb and put fresh oil all the way around and it runs great. It is still not much to look at as it needs tires and new plastics but it runs forward and reverse and the ugly tires hold air so there is no rush on spending more money. I am in the Chico CA area.
