That link I provided to Mike's carburetor shop is good place to email. I have emailed him and get good friendly information. He will know all about what you are asking. He has a video online on B carbs. Good guy. Expert. Send him ALL the numbers on your carb when you ask. There are several models of that carb. He knows them all. I remember him saying that the accelerator pump rubber is ethanol safe, I assume the needle rubber is the same. Ask him that also.
In my opinion, if the steel valve is examined under a magnifying glass and has no wear, that's one thing. Then you have the "seat" it has been matched to. If that is not worn, then that's another thing. If a steel valve set is mis aligned it won't seal. The rubber takes care of that as well as seals better. You will get a new seat with the kit also. What is your aversion to a kit? $22.50?
