BCS 290 two wheel tractor with no spark
I just picked up an old BCS tractor in a trade. The guy said it had a full service two years ago, but had been sitting for a year. He said it should run, and seemed like an honest guy, so I took his word for it and made the trade. When I got it home and tried to start it, I got nothing; not even a pop or sputter. so I took it to a small engine repair shop out in the country, and the guy said he'd never seen one before, and after cleaning the carb and trying to start it with no success, he stopped and said he'd need to charge more to take it apart to find an electrical issue. He says there's no spark. I think I should be able to figure this out myself, with the help of somebody thats knowledgeable about BCS ACME engines. Any advise would be much appreciated.
