I don't know how you could tell by the picture.It was just a blur to me.I'm not even sure what Fred was attempting to point out ??Maybe welds on the counter weight or something, not exactly the same as welding a pin.
To further add to my confusion,how much would a person actually gain with approx 75 thou more stroke?It wouldn't be much much. Unless this was a method to increase the comp ratio without building a removable head.
Now don't get me wrong, it's interesting conversation but I don't get the big picture I guess. On an old Mac I do get it.With a stroker and a giant overbore you can pump a 101 out to over 8 cu in but that's a lot different than just a scant few cc's on a Husky engine.
I have visions of those alledged shade tree mechanics attempting to file out the hole in the wheels with a round file or something.Then reassembling the crank with a big vise and a pair of 4 pound brass hammers.Ha,this I gotta see.
