Has anyone ever set one of these up before? I had a dealer sell me one as a stock replacement but it is no where close to the same internally. I have ordered 110 main and 17.5 pilot jet's but looking at the needle and slide they look different and I am not sure if they will work properly. How do I identify the stock needle and slide to order the same one for the new carb? I am assuming the same sizes should be close on the new VM 20. Any help would be appreciated.
