A non pictorial update on the corrective repairs. The Shiny new Piston has been installed.
Had to ease the fit of the Gudgeon Pin as it was tight in the new Small End Bearing.
I had swapped the new rings that were in the engine over to the new piston. Turned over real smooth by hand and nice compression.
Started 2nd pull, a small amount of fine carb adjustment made it run perfectly. Vibration issue sorted.
Spent most of this pm installing the back up Cylinder (Reel) and Drive parts. Now back on it's replaced wheels (and rollers).
Plenty of clearance now between the Blades, Underside of Deck Panel and B/Blade adjusters.
Just the fine adjustment to the cutting/scissor action do, and they already look pretty parallel to each other.
On the downside, The paint is lifting around the neck of the Petrol Tank !.
Must either be a pinhole in the Soldered joint, or the paint/Fuel proof lacquer did not bond to the brass well enough. Repaint job .
Had over yet again!, found that the 0.030" oversized piston came back with Standard size Rings fitted !!.
Good job I took them off and checked them in the new re bored Cylinder for the spare engine.
Ring gap should only be a few thou, not 0.125" !.
You have to be so careful nowadays, sadly, it seems you can't rely on anyone.
Now we have had some rain, I'll do a test cut when the grass begins to grow again.
