OK, you have tried a different carb with the same results…Yes, fuel flow is often an issue for these engines, and I have been fooled/stumped by goo in the copper line as well. Is the engine new to you? Has is ever run OK for you? Like Frank says, time to go back to the basics starting with compression. Are you sure the fuel supply is clean and fresh? Any signs of water on the plugs? Perhaps you have a leaky/blown head gasket. Does it look like the intake manifold has been messed with? Reed problems are rare on these engines, unless someone has messed with them or screwed up the gaskets…
