Given that you have done next to nothing to the engine for 3 years, think about this.
Before you dig into the carburetor:
-Check to see if the flapper valve in the manifold is free and that the bi-metallic spring is in place and in good working order.
-When you start it when the engine is cold, pull the choke out where you normally do, and pull the throttle out a bit to provide for RPM above idle (650-700ish). Once the engine starts, slowly push the choke in with the goal of pushing it all of the way is within less than thirty seconds. The above mentioned throttle knob position should provide for enough gas to keep the engine running well.
Doing these things may solve your problem without having to dig into a perfectly functioning carburetor.
How does it run once it it warmed up?
Does it leave black marks on the pavement once it is thoroughly warmed up by driving it around for a while?
