Ahoj
Po dlouhém plánování jsem začal stavět dvoudobý benzinový motor Felgiebel. Připravoval jsem se na stavbu motoru dva roky a poté, co jsem dostal plány, zkušenosti s konstrukcí dalších motorů a pístní kroužky, mohl jsem začít svůj nápad naplňovat. Svou konstrukci jsem zahájil vytvořením válce.

Motor má neobvyklý objem válce 16,6 ccm, protože použití prstenů pro větší vrtání. Kroužky o průměru 26 mm jsou pro mě nedostupné, protože jsem použil možnosti prsteny o průměru 28 mm.

Kroužky jsem koupil od české firmy "Piston Rings Komarov s.r.o". Právě kroužky jsem začal shánět jako úplně první a od rozměru kroužků, které jsem sehnal jsem upravil obsah válce.
I bought the rings from the Czech company "Piston Rings Komarov s.r.o". Just the rings I started looking for the very first and from the size of the rings that I got I modified the contents of the cylinder.
 
I fit the transfer channel to the cylinder. Now I'll try to make a new carburetor.

Very neat work. I am envious.

Cheers,

Extension of carburetor throat-attempt number two.
The throat had to be repeatedly heated by the burner to light red and then tap the thorn with small knocks.

Preparing for soldering.
I made a fixture to attach the carburetor to the cylinder. It holds the transfer channel itself as it is pressed. I insured him with a wire anyway. After a long deliberation, I made an unplanned exhaust flange.
Before soldering, I coated the soldered places with a mixture of borax and alcohol.

I can provide my own sketch on the flange.

Cylinder just after soldering. He's not cleared of borax yet. I soldered with silver, soldering itself lasted about 30 minutes and there was no need to heat the cylinder red.

A tricky brazing job and well executed. Did everything end up in the desired positions?

No, thanks to the necessary preparation, nothing moved. I was surprised how everything went according to plan.
Perhaps only the exhaust flange wanted to secure against sliding down.
 
I never used Borax, but the flux I used from Felder was quite well removable with a 15% sulfuric acid. Heated up to about 30-40°C. Take care, use gloves and glasses!
