I have a Workhorse also , it may not be the same engine , I have the Kawaski 13 hp 2 cylinder 4 stroke , I have to choke it if it has been sitting up for a couple of days , it fires right up with the choke and is ready to go in a second , if it sits a day it will start up with no choke and be ready to go , ------------- you both saying that the air filter has to be removed to start up easily makes me think there is not enough compression to suck the correct amount of air into the mix or your air filter is causing a restriction of air flow --- a K+N may help
