CSN carb seting

[Terminator84]

Hello, I am posting the topic to help others who have bought this type of carburetor. It is a CSN high-efficiency carburetor. When ordering, it comes without instructions.at least I have two free holes on the body, one vacuum is the other is connected to the fuel tank, both are connected and if you do not know the engine works very badly, but when you connect them by applying gas and load it goes out.I thought and thought to put a valve from the venous system through which you can regulate the flow of sucked fuel in general the vacuum sucks fuel from the overflow of the faucet and plays the role of an accelerator pump the engine accelerates very quickly but very little.

That looks like a cns carb, I have owned several. On mine the overflow is on the bottom of the bowl, I see it in one of your pictures. What you're call the overflow is the bowl vent, I used a small engine fuel filter as a vent cover.

Here's a exploded view from grubee.

Това прилича на cns carb, притежавал съм няколко. На моя преливникът е на дъното на купата, виждам го на една от вашите снимки. Това, което наричате преливник, е отдушникът на купата, аз използвах малък филтър за гориво на двигателя като отдушник. View attachment 105367

Това е точно моята идея, като свързвам маркуча към вакуума след определена скорост, вакуумът изсмуква гориво от преливника и един вид действа като ускорителна помпа, тъй като накарах двигателя да започне да ускорява много бързо.

This is exactly my idea, by connecting the hose to the vacuum after a certain speed, the vacuum sucks fuel from the overflow and a kind of acts as an acceleration pump, as I made the engine start accelerating very quickly

The biggest problem I had was with the bushing between the carburetor and intake deteriorating, I made a copper bushing using a plumbing fitting. You can see it in the picture I posted.
