Richard, I'm not sure it this will help much... Russian customs are extremely stupid and greedy (((
Since I have initially ordered two HFS-3 kits (one for my friend) - I will compare my valve with the original one and will send my own for repair if it is really bad.

The mix that caused problems was with additive of valve cleaning fluid.
I thought it is based on spirits only as per ingredients list, but seems like this list it was lying ((((

Today I was driving with fixed valve on pure water and it worked fine!
Tomorrow will do test on 99% methanol and will see if anything is wrong.

The only thing I am really worried about is the problem with non-working restrictors...
