Inquiry (采购产品): Rebuild kit Hello-I have model #2623cef-32. It worked perfect from 7/11/05 until 11/01/05. I bought another as I need 24/7 capability to run heat exchanger. I took off head and it is evident that piston "ring"seal is bad. I need rebuild kits. WHere-how-how much please. Great little unit by the way. Thanks a lot-Bill **** Hidden Message ***** William Farnsworth RR2 Box 3349 Pa Company: Farnsworth Art Glass E-mail: vegetron@aol.com **** Hidden Message ***** vegetron@aol.com
