I have a 1995 Toro Proline 52 inch cut with a 18 hp Kohler engine. The problem is it will not run smooth without being 3/4 choked. If I unchoke it it will bog down to almost stalling out then pick back up again and backfire. What gives? And in your opinion is this a good machine and what is it worth if I was to sell?

Does this mower have a fuel pump? I wouldn't know. It is probably your fuel pump (if it has one), your fuel filter, or carburetor problems. I would check if fuel is flowing through your fuel filter well. Then I would try cleaning the carb out (take the bowl off, spray a lot of Carb Cleaner everywhere, and blow through the jets and everything with an air compressor).

I'll be surprised if it isn't one of these. GL

Ya, sounds like the carb may be plugged up. I would look into the filter and make sure it is clean and replace as necessary. I would recommend taking the carburetor aparts and giving a thorough cleaning, maybe even a kit if it necessary, but it is deffinitely a fue restriction problem.
