I have two 20hp v twins here. One is on my grass cutter
One model # is 406777 and the other is # 457777 what's the difference??

So they are the same?? :confused:
I thought one might be a bigger CI.

Are you SURE you have a #457777???

My bad it's a 407777. I didn't clean it well when I looked at it.

They are both 40 cubic inch engines, the "6" & the "7" are the "basic design series", I have yet tp get anyone to tell me what that means?
