Recently picked up a model 8240 for $15.00, which was sitting at the end of someones yard. Started right up and ran fine, if not a bit loud. Replaced the plug, found a NOS replacement muffler on the net, new blade, and opted for steel replacement wheels. Cleaned the air filter and removed excess dirt with engine cleaner. The deck has a very small crack on the outside edge, where Lawn Boys typically rub fences. I've heard of a product called Alumaloy, sort of like a braze, with which I plan to make the repair. The latch to keep it out of self-propel mode is broken, but, despite the fact that the rollers are very worn, it propels itself very well. I really like this mower but I've come to learn about the dreaded "BBC", which I must admit, is a concern. Any advice/opinions are welcomed.
