Hi Knut,I guess you refer to the viton tipped float needle. If carb bodies are original, they will probably need to be sleeved. I have done the same with Concentric carbs. Throttle valves should be hard cromed or replaced by valves made of brass as in new Monoblocks now offered. Rattling throttle valves will affect fuel mixture and if they allow false air to pass, mixture will be too rich I think.
who supply the new throttle valves for monoblock?
