I'm just beginning to feel like working on this project again. Had back surgery two weeks ago and even though I'm in pain from the surgery the results are positive. So I worked on my 147 H today. Installed a starter switch. The key won't engage the starter. No big deal. It worked. After I got the motor running I noticed a huge leak from the carb. Tightened the bowl and and it still leaks. The bowl gasket is shot. I think I need to rebuild this carb. The carb itself has the raised letter/numbers and is a model C-275369. Where would you recommend a good source to buy a quality carb kit? Do I use the carb numbers or should I use the engine model number to get the correct carb kit? The engine is a Kohler K-321, 16 HP. I appreciate you assistance.
