snapper with wisconsin robin 4hp

i was just wonder im thinking of buying a snapper selfpropelled mower with a wisconsin 2 stoke (its in great shape starts on first pull ) my front yard is zoysia grass very thick i own a craftman professional hi vac with a 6.5 honda motor which is five years old it cuts this grass no problem iv never owned a two stoke mower will this 4hp wisconsin motor have enough power to cut zoysia grass my old 5hp commercial toro which it was a 87 model self propelled struggled cutting it any input would be appreciated i have pic of the snapper and my craftsman attached

I ran a 5hp Robin 2 cycle on a push Snapper for years, mainly working on some thick centipede and later a yard with mixed centipede and some other "trash grasses" like bahia. It never grunted, was great. Carburetor went bad, and couldn't find one for less than $150 and nobody would rebuild. I sold it for $30, but miss it.....
