Looking for new: .049 Mcoy glowhead

The plugs your in search of are in fact somewhat hard to find.Another concern I would have is your location of the world. If the plugs are difficult to find here, I would think your going to have an even tougher time finding them. They've been out of production for a long time. I do see them showing up from time to time typically on Ebay, they do tend to bring a fairly high dollar amount. Mecoa has made plug adapters for use in this and other engines. http://www.mecoa.com/acc/adaptors/index.htm The main problem with using a standard plug is the power loss. Not that the Mccoy was a powerhouse, just understand that there will be a drop in power due to the area within the glow plug is reducing the compression. Ken
