I have 2 45's that I plan on running on my new woods motor, but they are not dual's. They are both singles. I don't figure I would have to do much to make them work as a pair. Make sure they both have the same jets, venturis, and so on. I have heard some people say to "fill in" the holes in the throttle blades, and others say not to worry about 'em. I tried to run them as a pair about 10 years ago before I was very carb savy, and had no luck. Then I got webers, and HAD to learn carbs
. Any suggestions?
