My father-in-law has a 345 that is hard to start. When it does start, it takes a lot of throttle "nursing" to keep running. I took off the hood and the access plate in front of the carb/muffler area. I noticed the carb leaks a little fuel around the top of the float bowl where it meets the carb body. He had a small engine mechanic go through the carb last year and said it ran great during last years snowblowing season. After the snow was gone, he parked the machine for the spring and summer. Now he needs it up and running for this years session of winter. And guess who got nominated for fixing it? So, does anyone out there have any ideas on the fix for this tractor? I know he is pushing for a carb kit, but it sounds like it may be something simple to fix. (Me and carb work are not the best of friends).
