An update:
A project that challenges my patience

Hi Minh Thanh,

How do you plan on doing the injection pump for this one? The original Gardner pump is to my knowledge inline jerk pump with helix control, quite different in shape from the valve lash controlled type in your single cylinder engine.

For best running it will be necessary to balance the injectors so each cylinder receives a similar quantity of fuel.

Some pictures would be easier.
Don't look at other details, focus on what you need. - because there are some parts not shown in the picture such as springs, ... camshaft is just a symbolic shaft
If you need any information, please ask

Thanks! I think I see how it works.

Your craftmanship is outstanding. Some pictures of your setups would be appreciated.

There is still a lot of work to be done by hand
- Sharpen the edges but I don't know how to sharpen now

I just temporarily sanded the surface and sharpened the edge to see how it would look and let me have an overview for the next step : head cylinder

Hi all !
An update :

After a lot of worrying about the space for the injectors, and changing a few sizes when machining as well as changing the design of the injectors and after testing I feel fine.
Time to beautify the surface and drill holes for bolts...

Key for injector

An overview

Hi all !
An update :
There are a few places I really hate even though it's a bit hard to see, so I decided to "sculpt" to make it more beautiful.
I made a very sharp chisel and made it beautiful by hand

 

[Basil]

Very nice! On the little Honda GX engine there were some features that were frankly much quicker and easier to sculpt (by that meaning a hacksaw, a file and maybe the odd specially ground chisel) than go through endless setups. Complicated casting features on the crankcase I could only get so far with on manual machining. Just a little bit harder material to whittle down than wood!
To a large degree I guess the casting forms were sculpted which is what makes them so tough to replicate without a CNC.

Hi all !
An update :
I just did a preliminary lapping for the nozzles, when I make the injectors I will lapping the needle with nozzles

lapping tool :

Hard to tell from the picture but is the lapping tool split?
