Genuine Solex needle and seat.
Urban legend? For years, a few customers steadfastly swore the needle and seat supplied with carburetor rebuild kits was inferior - so much so, they refused to use it and put the old used one back in the carburetor.
We here at Zims have a soft spot in our hearts for folks willing to take such drastic measures. For the benefit of the truly hardcore, we have miraculously sourced these Geniune Solex needle and seats.
Our suggestion? Buy the carb kit for the gaskets and install this Genuine Solex needle and seat. All kidding aside, we base this suggestion on the Genuine Solex needle and seat features:
Fuel openings .25mm larger
Anti-vibration ball in top
Interior seals made of rubber
