86 Toyota pickup, 22R, 218k miles...

So, I one day decided to rebuild my carb to see if I could get better gas mileage (only was getting 15 in the city)... I did this and now have these four problems. I'm kind of at my wit's end with these... so anything you can do to help would be great.

1. Bogs at throttle tip-in. Recovers immediately after and revs nicely. Things I've tried: ground ICS, vacuum line check

2. Bogs when approaching secondary activation, at about 2/3 throttle. This bog does not go away, and if you floor it from a lower RPM it will stumble and not increase RPM.

3. Choke does not work anymore. Have checked all vacuum lines and linkages were not touched during the carb rebuild, just the two you have to remove to take the carb off.

4. There is gas in one of the HAC vacuum lines. I have no idea what would cause this.

For all of these issues, here is what I have checked: vacuum line routing, fuel level only slightly higher than middle of sight glass.

Other than these issues, the truck runs quite well, just not as well as before the carb rebuild

Gas in vacuum line can only be coming from the float bowl. Is it a stock carburetor or a weber or something else? Metering rods maybe? Power valve? It must be smoking when it Boggs. Right?

Its a stock carb. Metering rod seems to be installed correctly, including the little spring. Power valve was replaced with the included assembly in the rebuild kit. It actually doesn't smoke when its bogging, nor does the fuel level vary significantly in the sight glass. I guess a better way to describe the bog would be a fuel starvation. As soon as you back off the throttle onto the primaries, it recovers.

The only other way I can conceive of gas getting in a vac. line is a bad check valve or misrouted vacuum line. Try pluging the one with gas in it and see what happens. It must be robbing fuel at times and starving the engine.
