Default RE: Old engine start

Does the throttle barrel rotate easily? Often, if the former owner used a castor based fuel, the throttle barrell will be frozen, usually application of heat will free it up. If not soak overnight in fuel or plain old denatured alcohol then heat and try again. I'd diss assemble the fuel tank, clean it out with alcohol, replace the line on the clunk and possibly the fuel stopper if it is stiff and nonpliable. Remove the glowplug and possible the back cover of the engine and rinse thouroughly in fuel or alcohol. Make sure the passage of fuel through the needle valve is free (can you blow through it or squirt fuel through it?). After all this, open the needle valve about 2 1/2 to 3 turns, fuel it up, connect a new glow plug and prop and give it a try.
