VW, it’s quite likely going to need a carb rebuild or it will be leaking gas all over the place before you even try to start it. See the website Chris listed above. The carburetor has leather primer O-rings in it which are usually bad. The motor won’t prime if those are bad.
However, on the left side of the motor there will be a small L-shaped rod…it’s the low-speed carburetor needle. Open that up 5/8ths of a turn open from gently closed. On the right side of the motor will be a dial. Set that to about 3/4ths of a turn open from gently closed. Pushing down on that dial primes the motor. Without the recoil plate you’ll need to wrap a rope around the flywheel and pull.
