Test your injector with compressed air, if it is sealed with compressed air it will be more sealed with oil.
Notice every small change as you improve and perfect it.
Keep going and you will reach your goal
Hi Grasshopper !
I only polish aluminum once or twice and very little
If it still can have lines and grooves - try polishing in the direction you sanded and at a slower speed, then at a higher speed to finish.
Hi All !
I've done the fuel pump cylinder but haven't lap yet
With some testing, I found a pump cylinder length of about 8 to 10 mm to be fine - because the plunger stroke is very small - about 1 mm, but I wanted the best I could so I made it almost 2 times longer.
In my opinion, if 3 cylinders are all on a circle and the connecting rods of the left and right cylinders are also on a circle with the center of the connecting rod in the middle, the length of the connecting rod and the compression ratio is same
That's a pretty good question
When I post photos here, I usually try to limit posting - but it's hard to know what is enough !?
( It's a bit different when I post on facebook groups, I usually post all the pictures I can take)
If post too much pics , it will consume the forum's data...
I'm a bit late to reply, sorry.
No, it's not necessary
I sharpened it to the angle of the needle and sharpened it with a file - making a place for the abrasive to stay - it's made of steel
I tried with aluminum, but it's too hard to do and it wears out too fast
Why does the engine have radiator fins in the picture but not in the video
The radiator fin is a very important part because it determines the temperature difference between the hot and cold areas.
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
