RE: Advancing timing?
Aviator,
Check to see if the coil is attached to the cylinder. If not you will need to buy electronic ignition or use gas/glow fuel mix. Many Poulan saws don't have bolt on carb assemblies. This makes it harder to attach the carb. I have a 40cc pro that has the coil attached to the cylinder, but it took a CH ignitions manifold to connect the carb. It is a good engine, made in Sweden with a chrome bore. It may be better to keep it as a saw.
