Looking at the FSM and there seems to be a counterweight behind the flywheel??
There is one (or there was one) on the other end of the block. But not behind the flywheel.
cheers
I think if this is the standard flywheel its weighted slightly whithout the use of a counerweight itself, i think the large counterweights are used if the flywheels are super light to counteract the loads from the eccentric shaft??!!!
Counterweight is used for autos and aftermarket flywheels, the stock fw has it built in if you like so yours is fine.
cheers!!.....
