Hi guys! happy holidays. The kohler 18 HP and the 20 HP are the same bore and stroke (the 23 HP is a bigger bore... he he he) I think i may have a bead on a kohler that is in my price range. I looked up parts numbers and i cant find any discrepacies. So tell me, is it the carb? is it the exhaust? is it the timing? is is the cam? if i have to rebuild an 18 may as well make it a 20 right???? Thanks in advance and what are the part numbers?
What is the displacement for 23HP? 18hp is 570cc I believe.Originally Posted by spookum
18 and 20 hp are 627cc...
J dont you sleep? Idd print the parts pages for both engines and compare #s. I think its the carb. Guess who has a new 20hp carb on the shelf. 20hp mag. mod #M20S Spec #49521 Serial #2020110876 This one is a couple years newer than yours but will work. Merry Christmas
To whom are you referring about sleep? I worked midnights and am not smart enough to stay outta the garage and goto bed before I go back in for another one.
Would the 20 hp carb be for a Vangard? if so it should fit the 18hp I run with (2001).
The carb is for a kohler magnum 20. I look at post times and see all hours day n nite. Spookum is building a magnum from parts.
