The V-30's I have purchased (non-backplate versions ) have come in a plastic box with a pressure fitting, and a short piece of red tubing, but no T fittings? I've been using Perry pumps since they first came out (mid 70's) and they work quite well...

The older ones have a brass hex head adj. screw, and there's typically about .100 (give or take a few thou) between the inside of the screw's head and pump's plastic housing.

The later ones w/ the Allen wrench adjustable "set"(?) screw adj. screw I usually back out to the max. recommended amount (don't recall the exact measurement right off hand ) and just leave it there.

Most of the time, with the Perry pump carb, the high speed needle is only open about 1 turn (if that much ) and the idle disk is rotated toward lean about the width of the slot in the disk.

Non Perry carbs can be hard to adjust, especially in the mid range...and certain later model O.S. carbs in particular.

A friend and I have gone round and round with this problem since the pumps were introduced, and after fiddling with the stock carbs, have almost always found that the best carb is the Perry pump carb. (the K&B .61 and Webra Speed .61, and O.S. .60-.61 FSR came with a pump "kit" that included a backplate pump, and big bore carb, as a set...that was/is IMO the best way to go...too bad you can't get the backplate style pumps anymore )

mosand...all of the FX style carbs I have encountered have a rich mid-range, with or without a pump, so you're going to have to lean the low speed quite a bit I would guess...it's just going to take some tweaking.
