Hi all, if I can trouble you once more, after succesful replacement of impeller and a few other items at the same time, thanks to the help kindly offered from you guys, I fired her up, and she runs sweet, however I noticed a small oil leak weeping from under the engine cover. It's not a new leak, I noticed it last season, but I thought whilst I have the chance to do something about it, but not having the benefit of a service manual (yet), all I can say is the leak appears to be coming from somewhere near to the carburretors. Any offers of a likely cause /repair?
