Default Re: what did you do to your motorized bicycle today?

Those type carbs are Very nice because you can fine tune them without taking them apart and it's that fine tunability that's why they run and perform so well. I've seen a few people who drilled and tapped a hole in their case near the transfers to install a niple and run a pulse line which makes these work even better. Somewhere I've heard the JNM wlabro type carbs have been modified so they don't need that pulse line but I'm not sure how that's supposed to work. I know on a lot of chainsaws and other small 2 smokers they sometimes have a spacer plate that channels the pulse line into the manifold to eliminate needing a separate line.
