Carbed 4 strks are 10x worse than 2 strks. To meet emissions the the idles are leaned out so far they are prone to plugging up the jets. That is common knowledge and a lot of times carb replacement is mandated. So no they are not the same as 2 strks.
Remove the kill switch completely and use the choke to kill it. You cannot use an ignition to ground kill switch on that motor. That is probably a phasemaker ignition and it will get expensive fast
