no primer bulb on briggs & stratton lawn mower engine

Forum Newbie
i bought a used bolens lawn mower today with a briggs & stratton engine.. the engine model number is 128M02-0952-F1.. it also has april 2012 stamped on it.... it is in good shape.. it started up on the second pull and i bought it.. i can't find anything online about the motor except for parts... there is no primer bulb or throttle on it ... does anyone know why this is and can anyone tell me what cc engine this is.. thanks
 
It probably doesn't have a primer because it has an Autochoke that works off of heat from the muffler. Cold, choke closed, Hot, choke opens.
And probably no throttle control as most are fixed speed (usually depends on the Mower manufacturer) but you can usually adjust the rpm by bending the tab on the front of the engine that the governor spring is hooked to.
And i believe those engines are around 190cc 5hp or so.
 
hey thanks for the replies.. the fellow i bought it from thinks it is 140 cc... sure wish that link would have come across Star Tech's thread
