RE: Why not a Webra engines thread?
I had heard that the Dynamix was difficult to set and operate. Talk of pumps and endless headaches was the norm. They even said there are only two carbs that had to have articles written about them, the Fox, and the Webra Dynamix. I was a little skeptical to try one, but I wanted to see if I could run one of the darned things. I am so glad that I did!
I have never had to use a pump with a dynamix carb. I have used them on Webra Speed .32, .40, .50 .61, and even on a few other brands of engines. They all performed well and had tha instantaneous transition that the Dynamix offers. In fact, I consider the Dynamix my favorite carb. I hope you are able to try one and have similar results.
