Grumpy, no these are not old pic's, The con rod & piston I used previously were out of my spare engine that was in pieces.
This is a complete engine that I have opened up for the first time today.
I have heard it running when I bought it, it blew black smoke & was started with a small spray of assist.
I will check the rings for matching scratches.
I will hone the bore & replace the rings.
The valves are another story, I have only just got a lapping stick & paste, I have watched a few U tube videos, thats the extent of my experience here.
You might find it funny but I had to google "crank pin" this weekend because to me its not a pin.
Here are the images of the smokey engines bearings to compare.
Great stuff, I set aside this weekend to sort out these engines so I dont have to push my super 24inch 2 strokes as much this spring, I will be able to sit down & mow.
Thanks for your words & help this weekend, another week of work & I will attack this engine again.[Linked Image]
