So we've got a very nice rider but it smokes like a steam engine! It runs pretty well but not that well. I'm thinking of doing an overhaul, or at least tearing it apart for inspection. What's the story on these B&S twins? Is it worthwhile or should I look for a not-so-smokey donor motor on Craigslist? Are new valves gonna help if all I can do is spin them with a drill motor and a little grinding compound? Are there guides / stem seals? Will an automotive head shop work on these? I've torn down a few singles and swapped parts around as a kid but never actually bought new parts to try and revive one for real. Am I wasting our time?

go to jackssmallengine.com. They have new engines on special at a price cheaper than rebuilt. Full two year warrantee.
