I have heard alot of stuff about tilly carbs that if you dont know what you are doing tuning wise you shouldnt mess with them. Is it trully that hard to tune the carb? I was thinking of using a 360 gas tillotson for my 5 hp briggs that will have a 233-ss dyno cam. Is there any tricks to this? Can a person do it or do I need someone that has tons of expericence with them?
