Follow up on Zenith
 

Put the kit in the zenith this morning. Replaced the float valve with the better valve. Runs better didn't stall at stop signs, it does backfire a little when I let off the gas to shift gears. Also there is still a little bit of gas on the bottom of the carb after I turn it off and let it set unless I shut the gas off. Suggestions?

Maclab58,

Whenever I park mine for more than a few minutes, I first shut off the gas valve under the dash - then let it run for 20 seconds or so. Then I turn the key off.
I never leave it sit for very long with the under dash gas valve left on.
Just a habit I've gotten into.

These are updraft carbs, when you turn the car off you can get a little gas to drop out of the throat / intake vertical area, not much but enough to show a little gas in the throat / choke area.

I came out after 20 min and there was a 6 inch gas spot on the driveway. Drove it again and still pops when I let off the gas to shift. Disappointed for sure.

How much do you have the GAV open?
If it is too shut down you will get a "pop" when you back off the gas.
Did you clean the GAV port / path?

Yes, cleaned the GAV port. May have had to turned down too much. I will readjust the float again tomorrow in hopes of getting rid of the dripping gas. Will keep y'all posted.

Get into the habit of what Jtomas6 says in #2. The shut off valve is the shut off valve the float valve is metering device. Back firing on changing gear may be a weak mix within carb - try enriching by turning GAV knob a tweak, or may be a weak mix outside of carb(!) eg slight air leak on carb/ intake manifold or intake /black manifold. Also sometimes different brands/grades of petrol give different characteristics.
