Re[2]: T'Quad mixture screws

     John,

     Rebuilt the carb about two months ago.  Ran great till last 
week.  The secondary jets are controlled by vacuum operated 
needles that adjust automatically.  The carb is clean, the 
secondaries are the problem.  Worked the carb from inside the 
hood.  I didn't dip the carb when I cleaned it, I pumped the dip 
through the orifices.  This isn't the first carb I've done, but 
it was certainly one of the easiest.  The inside of the body 
really doesn't have anything in it.  The old gaskets (previous 
owner) were the 600cfm size, and they actually stuck into the 
throats almost 1/8".  I installed the new gaskets (~700cfm), 
needles, seats, o-rings, floats, and it ran like a champ.  The 
accelerator pump works fine, so I'm guessing that there is a 
problem with the secondary valves into the horn in the throat.

     I'll check delivery and pressure in both states (new/old 
filter) tonight and let you know what I find.
