Just got a call from the shop that is putting a carb kit on my C5 Homey. They tell me that the carb will not seal and that it is leaking gas. Said they have done all they can and asked me to come pick it up. This saw ran fine last season. Is it possible for the cylinder to warp or the carb base to warp in that time? I am not a wrench so tend to be clueless and have trusted what these guys have told me in the past. They are going to charge me for the carb kit only... What would the carb kit typically cost for this saw in a shop and is there anything else that could be done to save this old saw that is not going to cost a fortune. I hate to scrap a good old saw like this.
