The only way I know of to check how much R-134a is in the system is by pressure. They use a scale on the filling bottle to know how much they have put into the system, so the # of lbs comes from there.

It sounds like you need to top off the R-134a in your system to the point where it doesn't cycle the compressor clutch. It sounds to me like it's pumping until the low refridgerent switch turns the system off, and when it builds up again, it lets it start again.
