Cogsy,
Thanks for your comments and advise.

Bellow is a photo to show the finishing I got on piston liners.

The way I machined the cam lobes, the end mill produced a crown on the base of the lobe, you can see it on the photo bellow.

To remove the crown I grinded the lobe moving the grinder chuck by hand from one flank to the other flank. See the result bellow

Boring the piston pin hole

Alining the bore to machine the slot for the conecting rod

Then I took the piston to the lathe to remove the epigot used to hold the piston on the milling vise. I used the pin hole as a stopper to ensure all the pistons had the same dimension from the center hole to the top of the piston

As I said before, see bellow some videos of Distributor Gears Being machined on CNC Rotary Table

This is not the final Gear. It is only a sample to test the G-Code

Hi all!
I have a question and need help from you all.
I'm now ready to install the eletronic iginition and the CDI supplier sent the following notes with the kit regarding the Hall Sensor
IMG_20180408_215807996.jpg

The plans call for this
IMG_20180408_215229211.jpg
IMG_20180408_215534051.jpg

The hall sensor is in contact with the metal from the distributor case.
How do I proceed with the installation of the hall sensor?

The ones that already built this engine could help?

Thanks in advance


Edi

Hello CS!
Thanks for your note.

Have you fixed your sensor like I showed on the pictures? Did you glued the hall sensor on the small Strap/Tab?

One more advise about the contact of the CDI spark to the distributor rotor contact. :confused::confused:
Please see picture bellow for better understanding
Distributor Assembly.jpg

Thanks,

Edi

Hi again Edi.
No contact just a small airgap and the spark will jump. ca 0,3mm:thumbup:

nice set up:thumbup:

personally, to play it safe because those hall sensor are quite sensative
to back EMF I would put a small piece of plastic behind it to isolate from the motor. one are two layer of scotch tape would do

Dears!
I'm here again to ask for help on the ignition installation. I'm a dummy about electronics.

I have a doubt about a resistor that come with the kit. Picture bellow
IMG_20180410_230706494.jpg

There is the following note with the resistor
IMG_20180410_230548105.jpg

Where exactly it goes? I'm really confused:confused::confused:Also see item C of the instructions
IMG_20180410_230816673.jpg

The last two pictures is to show how I think it should be installed. Is it correct? Where the resistor should be installed?

Thanks,

Edi

Hi Looks like the engine isn't far off being run will you be posting a video of it running?
Cheers

Hello Allen!
For sure I will post a video. It will be a pleasure to share with the folks here.
I plan to tray the first run this weekend, I'm very anxious to see it making noise. It is the first engine I ever built.

I really hope I don't face much problem (bugs) making it run.

Thanks,

Edi

Hi fellows!
I tried to start the TI4 today.
For my deception it did not started, even did not showed any signal.
I checked the ignition system including distributor, spark plug and CDI and found everything to be OK.
I observed that it seems that instead of the carburetor be sucking in, it is blowing fuel out.

Did I do something wrong on the camshaft?

Totally disappointed:mad::mad::mad::mad:

Thanks,

Edi

It could be that your valves are leaking though if it's fully exhausting through the carb I would suspect cam timing might be the cause. All I can suggest for now is to double check the cam timing.

Hello Luc!
I really feel sorry for that:wall:. Your help and suggestions are great appreciated.
I have answered your previous posts. Just skiped the last two. Maybe to anxious to see this litlle beast runing.

On post #172 I just forgot to tell you that I got a note from the CDI supplier that the resistor is not necessary for this type of distributor. He will not send the resistor anymore.

Regarding your post #170 I followed your suggestion just added a bit of super bond glue.

I hope you understand and continue helping passing me with your experience which is very valuable.

Thank you very much.

Edi
