Hi dmitr,
In your efforts to rebuild the carby, remember that service part
CR03773A is designed as a whole unit replacement for the carby. Consider the cost of the entire replacement vs trying to work with what you have. Please don't misunderstand, we're all about that service life and replacing the $2 O ring and fixing things, but consider that it may take several parts, several tries, and that may still not resolve the issue, and you may then bite the bullet and buy a new carby, which also may not resolve the issue because the issue was something else that has been missed. So just consider your options
Cheers,
