Hey guys thanks for all the info. I think I'm going to look into updating the carb with the pwk 39. What are the benefits of the newer carb, other than that fact it'll be easier to get parts. Update...... I've been told to run a pwk 38 by a local guy that says the 39 drains gas and the the 38 will run much better. True or untrue? I'm skeptical because he has a 38, but I could get it for $40. Is it an option?? Thanks again
