ROY i sent Gary i picture of the balance weight i made to smooth out the engine ,my k-341 didn,t come with balance gears ,how ever places the ,1/2 the out of balance to the side ,and not up and down ,and i did remove the pins .and and gears ,and replaces the pins with plugs,i didn,t want to use a chisel ,and take a chance on braking the case .there is more to this than ,making a plate ,you need to weight the rotating parts and cut that amount in haft ,and that will be your weight size ,i will sent you a picture .David
