Thamks,

Others have said the vac sec carbs work good with a 50cc pump, light springs and rich settings on the secondary jets.

The carb works pretty well now, just wondering if its justified spending big $ on a different carby for not much seat of the pants difference...



If that 870 is doing good & you feel you have it dialed in, i'd just leave it be & keep it, you may get another .1 & 1 mph or so from a different carb, but is it worth the 600.00 or so you'de have to spend, i say no, drop the bottle on it, that'll give you a nice for about the same price.
