I'm glad someone finally brought up these carbs. I'm on my second BG Speed Demon 650 on a 351W and still having problems. The first one's throttle plates would stick when the motor got hot but ran well otherwise after some jetting changes. The second one (with a wooden block) stopped sticking, but weeps fuel down the manifold from both float bowl seals. I'm not talking about alot of fuel, but enough to cause the red die that must come from the seal to leave stains on the manifold and tiny little pools of fuel in the valleys after a whole day of driving.

In addition, the engine starves and almost dies during hard stops. The float levels are good, yet if I don't heel and tow to keep the revs up during hard stops, it stumbles.

And lastly, this second carb doesn't run as well as the first one even though all the setting are the same. It idles and starts well, yet boggs sometimes under the pedal and never seems as 'clean'. My SPF has never been dynoed, so I have no benchmark to go with other than the seat of my pants, but last time I had it calabrated it was on the money...

Any ideas??
