Hi. I was recently looking at kohler build prices just to mess around and I was wondering if I could build a 30-35hp kohler more cost effectively than a briggs. I have a stock 33ci briggs with a flywheel as of now. Midwest super cub is willing to sell me a flywheel for 100 bucks. What would work better. If the kohler would be better, is there anybody who can port and polish a kohler head for a really reasonable price?
