had a though that someone else might have had this same issue and same thought process and may have already found a good solution
my cousin and I bought a pair of old bolens a couple years ago. We're pretty mechanical, however, these pre-date us by a few years. I took the 650, he took the 800.
His 800 has a wisconsin S8D, and the carb is about worn out. I think the briggs on mine is worse, but parts are a bit easier to come by. Rather than attempt a complete rebuild, we thought about trying one of the chinese made carb units. for the briggs they're cheaper than a carb kit..for this wisconsin not having much luck. Googling suggest carb might be a zenith 12982.
Has anyone had any luck finding a budget friendly replacement, or swapped to a more common carb model? If the mounting flange to the head is different we can work around that as he's got the fab skills and equipment to make an adapter plate, but linkages and physical fit under hood and around exhaust would be a concern. Appreciate any ideas anyone might have or any experience anyone might have to share.
