Thanks for the replies. I guess I better keep the 316. I have a young fellow working with for me and we got her running last night. sounds Ok. Now I have replaced the Gas tank but still woried about rust, have one filter up near the carb and i think another off gas tank. plan to run some gas throught and catch in a container and see what we have.The carb has been gone over by Jim Carter so don't want to plug up. Any advice is appreciated. tom
