Hello I need some guidence on a carb for my 59 235 motor Tried to start it this aftn and not good . opened the carb and it has dried out and the potmetal is all frosty. Lookes on line and a few places have new carbs for around $140. a rebuilt from classic is 240 . are these new carbs any good ? i figure they come from off shore. dont know if mine will take another rebuild. Thanks and have a nice weekend
