one of the throw off's on Grant's carbs was that they were good dyno carbs but at the track were quite tricky and actually did not live up to their billing. I've seen it personally. If you've got one, just work through the issues because in the end, a carburetor is just a box sitting on top of an engine that mixes the fuel and air it uses.

All you guys are shape as tacks, any one of you can make it work I'm sure.
