I always have a garden hose handy to aid in cooling the radiator, once the engine starts and the rpm up, it's best not to shut it down till the break-in time has pasted, the hose will keep the temp down if its starts creeping up.
Don't fiddle with it till it's broke in, make adjustments on the fly only as needed to keep it running, there will little to no load on the engine, so timing and carburetor adjustments don't need to be spot on.
Its rpm that throws oil off the crank on to the camshaft, so keep it up over 1800.
