It's quite hard to flood them, I find. But Dave, If the carb is empty, what good does it do to pump the throttle? > It's certainly easier turning the key on and off on a FI and waiting for the air > bubbles to stop bubbling in the tank.

My '68 used to "sign" for a moment, but usually after it first started. I believe the cause was the same, however. I really like the little pushbuttons I install to run the pump briefly before even running the starter; in hot weather I find that I really have to hold that down for quite a long time to get all the bubbles out. It seems to be much more effective than even a long series of key turnings. I wonder if one could hook up an electric pump with carbs AND the usual mechanical pump, just to run by pushbutton to get things primed. At least that would avoid the whole electric pump/safety issue. > An 8 yr old Interstate Megatron sounds more like a Dr Who monster than a > battery. ;-) ;-) -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
