G'day Andrew,
Your engine is a power torque 160cc?
The hose from block to the back of the carby is meant to provide a vacuum to control overspeed (vacuum vs spring pressure governer)
The self propelled operating lever up on the handles can be adjusted.
You can loosen the cable by undoing the 2 x 10mm nuts half way down the bars.
