<VV> Cutting Out in Turns

[Smitty Smith]

From: "Robert Hawley" 
Ok, I'll bite what is the "known problem and an easy fix?" for this problem. I've read Bob Helt's YH Tech paper and haven't found that particular problem addressed (or am I going blind?!). Does it have anything to do with fuel sloshing in the bowl or float issues? Any help to enlighten me about the solution to the YH cutting out during turns will be appreciated.

  Smitty says:  Here's what worked for me Robert.  And you are right, none of those sources cover the subject.  What is happening to make the engine cut out is not starvation but flooding from raw fuel being poured down the carb throat by the bowl vent when lateral forces slosh the fuel in the bowl.  (or drop the float down so uncontroled fuel pours into the bowl).
  On the left end of the carb on top there is a chrome plated plug about 5/16 diameter.  Pull that plug out.  Inside you wil see a port running down and to the right which is the bowl vent.  Running off of that port is one running down and to the left which dumps into the horn (mouth) of the carb.  Get a piece of 1/4 ID tubing about 6" long.  push it into the bowl vent port at least far enough to go past the port going to the horn.  Then bend the tube straight up.  As I have explained to others, there is a possibility of fuel fountaining up out of this new vent if the float is displaced and can't shut the valve off.  I have never known it if it did happen. If you are worried about it put a hose on it and leave it stick out the bottom of the car.  Generally speaking, if it is just fuel slosh, it is going to have a hard time sloshing to the top of a 6" tube.
