Thanks for the help. The problem was the spark gap, 1/4 inch stainless steel capnuts. As soon as I replaced them and re gaped it worked for another 15-20 seconds. Burnish them and they would last another 10 seconds. I built a pvc and copper pipe gap and it won't quit working. George... HAM=N4ZPO SGMET=#244 FCC=PG-5-6642 erc-at-coastalnet-dot-com
