now and then the new viton tipped float needles are sticking on one or the
other of my HS-4 carbs. When it happens if I tap on the top of the offending
carb's float bowl using a screwdriver handle and with the fuel pump energized,
the needle valve opens and I can hear the fuel pump fill the bowl. This
started happening in the summer of 2016. I replaced the needle & seat
assemblies in both carbs with aftermarket units. It didn't cure the
problem.</SPAN><BR

weeks ago I put in new OEM viton-tipped needle & seat assemblies. Then as
I was adjusting the jets both carbs ran dry & the engine stopped. So I
tapped on one carb bowl & then the other, heard the pump run while filling
them up. The engine then started right back up. Last time it happened I had
the engine warming up, running at fast idle when it started running very
rough. I Tapped on the front carb bowl whilst it was still running & it
smoothed right out. Same thing happened another time but it was the rear
carb.<SPAN class=Apple-converted-space> </SPAN></SPAN><BR

fuel pump is a ~5 year old SU with points. I measured the fuel pressure at the
carbs to be 4 psi on the nose and it doesn't leak down much or very fast. It
has a new inline fuel filter mounted just before the carbs. The floats are the
all-plastic type and they don't show any sign of leakage. The floats are very
free on the swivel pins and will drop to the stops.The swivel holes in the
floats aren't visually elongated and the swivel pins don't show appreciable
wear. The carb's vents are clear and I can blow air through the vent
tubes.<SPAN class=Apple-converted-space> </SPAN></SPAN><BR

thought maybe the 7 month old gas might be a contributor to the problem but we
put about 100 miles on the car last Tuesday after putting in fresh mid-grade
gas, looking at Hill country wildflowers. The car will maintain 70 mph in
hilly country all day. Ran like a swiss watch<SPAN
