I have my own machine tools, lathe and bridgeport and fairly good with wrenches. I trust nobody to do machine work especially since I am a machinist. Just thought steiner, asap or tm might have.
Thanks ill look around

He responds to most of my posts so ill let him chime in. Cant see letting a crack free block go dor melt down if i can save it. Plus it gets me a back up block
 
Last time I needed parts like that, the machine shop could source them cheaper and faster than I could.
 
exhaust seat 245-1187-1, make sure the main caps are matched to the block in the correct order, seats cut em out on the mill and press in new ones, for valves buy the kit it comes with guides, valves, springs, keepers, they made 2 different rods also and they need to match the crank as they are different where the radius is

I think I remember that the different rods are linked to the change from flat to domed pistons but I could be wrong. Stan
 
Hi,
If you put in new valve guides and valves, I think the Cub service manual says to measure the ID of the guides after putting them in the block. They may need reaming so they have the right clearance with the valve stems. Maybe you knew this already.
I remember in the past someone on here put new valve guides and valves in his Cub engine. He had it together and running again, and he said one valve would stick open when the engine warmed up.
He said he hadn't reamed the valve guide IDs.
I would read the Cub service manual, and check the clearances, like it says.
Below is the Cub and LoBoy service manual, it has lots of info.
I would read the engine section, section 1, before working on the engine.
There is a contents beginning on page 1 of most sections, that makes it easier to use online.

You didn't say the year of the Cub. This manual was made in the 1970's so it has newer, 12 volt electrical system info. :)
