I feel cheated because of the fact that the carburettor was supposed to be marked with JB - and it came not enough that after 3 months it was a simple, cheesy, badly made, scratched and vile cast aluminum - just such a cheesy can be bought for PLN 40, so I decided on the version more expensive but with the designation JB and I got a cheesy carburetor. I do not recommend - because they are cheaper in this quality.
