You can not see the fuel level in the float bowl from the outside on a Qjet. You however can see how well the accelerator pump is working by looking down the primary bores and winging the throttle open. You should get two good solid streams shooting across the bores. Weak streams in conjunction with a choke plate that is not fully closed before the engine starts can cause the symptoms you are experiencing.
If the pump seal lip has failed or as Old Blue K and I have said the check valve is leaking you will have a poor accelerator pump shot. So if the pump shot is poor the first step is to see if you have fuel in the float bowl and that means pulling the top off of the carburetor without spilling fuel out of the carburetor. I usually just do this with the carburetor still bolted on the intake manifold.
If you have enough fuel in the float bowl then it is highly likely the pump lip seal or the check valve is the culprit.
