Peter.
What is the oil consumption? and what do the plugs look like?
What does the compression feel like on the handle?
Do what you normally do, crank it for a bit, then takr a plug out. Is it dry or is it wet with fuel.
If its wet itll be an ignition problem.
If its dry, do a little test. Pour a thimble full of fuel down each bore, replace everything. Does it then fire?
Sounds to me like you could have compression issues and the engine has to build some by cranking before it will suck the fuel out of the carb. And without fuel, it wont go.
I've got one here with the very problem. It doesnt burn a hell of a lot of oil, but it does foul the plugs (H/C head) eventually. Keeping the plugs clean and priming the carb with the pump before a cold start save a lot of pain on the battery. I will put another block on it one day. Trouble is it goes like stink
