Anniversary of Felgiebel Today is exactly the year when I first started my first engine. I could now start to complete the project, mainly on the tanks and the engine bed. 😅

Work on the motor holder continues. I'm not an experienced welder, but it still doesn't look bad.

Of course, I didn't use the word correctly.

Production of engine bed. It is fired from 3mm thick iron sheet.

In addition to batteries, the ignition consists only of an interrupter and a high-voltage coil, both of which I made. In short-purchased are only piston rings, spark plug and of course the ignition supply. If I bought parts of the ignition, I wouldn't be able to call my ignition "home-made".

If you mean a source by this circuit, then the coil is driven by 4 NiMh monocells with a total voltage of 6V. The coil is 3-4V according to the instructions, but it hasn't burned yet, so that's probably not a problem.

The high voltage coil gave the engine the correct authentic expression, compared to CDI ignition, the engine heats up less. The needle and lead settings remained similar.

Felgiebel already runs with homemade ignition.

Yes, although I really wanted to, I was still not sure if I could build an internal combustion engine in amateur conditions and with a minimum of experience. And surprisingly, I managed to make it.

Today I ran again, this time earlier, which caused higher engine speeds. It should slow down the warm-up of the engine, which would prolong its operation, as a result, the engine can run at idle and high speeds for the same length of time, it heats up similarly. After a few starts, which lasted...

1 part oil and 3 parts gasoline is a 1/4 ratio. 25% oil, 75% gasoline.

Thank you for your praise. Now I will deal with the modification of the engine accessories to the original historical. Brass tank, original ignition, engine bed ...

I know that the piston is too tight, I was already afraid of tightening during production. But I prefer tighter and then grinding than looser and making a new one.

Indeed, the ratio of oil and gasoline is 1: 4, for the original, the run-in was 1: 3. Thank you for your congratulations.

It was around 8 ° C, Natural 95 fuel and M2T oil in a ratio of 1: 4. I finally used an electronic ignition, with an interrupter. I plan to release the high voltage coil in the future. I started the engine about 15 times today, each time for about 30 seconds, then it warmed up and started to...
