I am new to the site and I have read a lot of great info on here. But I have a question about my Cub Cadet. It has a Kohler 18hp magnum m18s from I guess the mid 90's. There are about 1045hrs on it. This is a mower that I got from my father when he passed away, it has been sitting for some time and all I knew was that it started smoking when he had. So I started it and there was a bunch of white smoke and would only run with it fully choked. So I searched and read to try and clean the carb. So I pulled and cleaned the carb. When I went to try and start it again the started wouldn't engage the flywheel. So I know I need a new starter to get anywhere. So here is my question. The plugs had oil on them and with the white smoke I am thinking maybe bad rings? Do I need to rebuild? When it did start the smoke would go away after running for a bit, it was fully choked so there was a little smoke. Where can I find a rebuild kit or a good site for parts for these motors/mowers? There are a couple things wrong with it so I am looking for somewhere to find parts. Sorry for the long post and thanks in advance.
