We've both got exactly the same 'model 32' motor. Mine is fitted with 15ft springs, but some were fitted with 17ft springs and would probably manage 4 record sides - the springs are in series. It'll say on the barrel if you look closely - there'll be a little number 15 or 17 stamped on it, but you'll need to look closely to see it.

Are you absolutely sure that your governor is working correctly? From stationary with the speed control set in the middle 78 RPM position there should be a gap between the disc on the governor and the felt or leather pad. When the motor starts, the three balls will spin out and pull the disc along the inner shaft until it touches the brake pad and that's how it maintains its exact speed.
