Stus-List Starting a Universal

For a new M3-20B, the Universal Operator's Manual gives a table that 
says hold the preheat switch for approx 10 sec if temperature is 41F/5C 
or higher, 15 sec if temperature is 41F-23F/5C- -5C, and 20 sec if temp 
below 23F/-5C.  With Universal-supplied panels the preheat switch has to 
be pressed for the starter button to work, and it (the preheat button) 
has to be held down until oil pressure builds up, other wise the engine 
will stop.

This was also the same info given in the operators manual for an older 
20B-2, which I think was about your engine's vintage, though some 
engines did not have the oil pressure switch feature.
