Since it's new to you, are you giving the throttle a pump or two and giving it some throttle to start, or are you just leaving it in neutral and cranking?

if you leave it in neautral it wont start but if you unhook the throttle and open the butterfly on the carb it will fire up

It's a carb, not fuel injection. Put the throttle lever in the throttle only position and pump the throttle and give it some gas.
