Hi Pikey, welcome to Outdoorking. I see that your SB45 has lots of meat on the reel (blade cylinder) but the chain sprockets are somewhat worn (though they still have life in them). These are usually the two most expensive potential problem areas, aside from the base engine, so your mower seems a worthwhile candidate for restoration. I'll leave it to Deejay, our reel mower guy, to discuss details with you and help you reach a decision on restoration. With regard to the Kirby Lauson engine, they have a water drain button in the bottom of the carburetor float bowl, and it has a tendency to drip fuel in advanced old age. You will need to remove the float bowl and look closely at the sealing washer that is built into the drain mechanism. The repair process may be a bit fiddly, but people do it successfully. I personally regard the water drain as not especially useful - you can drain the water by just removing the float bowl and cleaning it out - but if you plan a full restoration, it is best to repair the machine in detail rather than take shortcuts.
