I always do it by cranking. I have a pressure gauge right before the carb and I use a remote starter. First, I remove one sight plug and put my thumb over the hole, then I crank for about three or four seconds to start filling the bowls, then wait, and crank it a few more seconds until I see a steady 6 or 7 psi, which tells me the floats have risen and closed off the needle and seat valve. I wait a few more seconds until I see the pressure drop back down and then I loosen the screw and turn the nut depending on whether there was too little or too much gas in the bowl (it's always too little for me, as I set the floats a little low dry). Then I put my thumb over the sight hole and crank it some more, do the same thing again, until I get it right below the sight hole. I do the other bowl the same way. I never adjust them with the engine running nor with the engine hot. Now, later on, I do double check the levels after driving the car and letting it cool down but I never do anything with the engine running or when the engine is anything but cold. For the gas to be coming out of the boosters, there must be something wrong with the interaction of the float and the needle and seat valve. Or the gas is going right by the little black O-ring. That kit comes with a bunch of valves, more than they show in the picture. Did you cross reference the little markings on your old valve to the correct new one? Did you put a dab of Vaseline on the O-ring before you slipped it in and screwed it down? Aside from using the .097 when you probably need the .110, I don't know how it could be in wrong. How many threads are peeking up above the bowl with the nut off?

I wacked the starter a few times with a broom handle, but I probably need to get under there and really whack it with a rubber hammer, and probably take it out. Could it be the firewall mounted solenoid (it's only 6 mos old). I think i burned up the starter, fartin' around yesterday. thanx for seeing me through this saga. s
Well, if the starter is engaging, then the engine should be turning. Of course, that means your fan belt turns, your alternator turns, everything turns. If you suspect a faulty starter solenoid, try using a big thick jumper cable across the two large positive poles, for just a second, to see if the starter will turn normally. If doing that makes the same "high pitched spinning" noise, and you see nothing moving on the engine, then the starter is suspect. Dang, now is not the time to buy a lottery ticket....
