boothboy Once the carb is re-installed turn the idle adjustment screw about 1-1 1/2 turns to start opening the throttle plates. Warm it up and set with a tach to factory settings.

The mixture screws areīnt the problem, itīs when I have to up or down the idle a tad my brain never remembers where the original setting was.

Then I counted the turns to get the slots right, on this carb it was just half a turn, waaaaay off what I actually thought it was.
You might have to figure in the return spring tension when the carb is back on the motor, quarter turn I reckon.
In my case it didīnt need it.
Now if I lose my adjustment with the carb on the motor I can reset to just touching and add my half turn.
That is exactly what my brother showed me when I took the carb off the Gran Sport, count the turns on all the adjustments and record them so you can start where you were, you knew it was running, and adjust from there for the fine tune.

MARTINSR Randy was right, it was just a bandaid this time, so I pulled the carb and opened it up and cleaned it out, I also added a fuel filter, I didn't have one!

It runs like a champ now.

MARTINSR This is one that helped me last night when I put the carb on the Buick and fired it up. One day back awhile I was firing up the car for the first time after it had sat for years and right as I was cranking it an old friend came walking into my garage. This guy is a motor guy thru and thru and the first thing he asked as he stopped me from cranking was "Did you fill the carb with gas?" HUH? How do you fill the carb I asked and he showed me how you pour gas into the bowl thru the vent. Sure enough, it fired right up and kept running.

I did the same thing last night, it fired right up and ran.

In this pic I used a valve cover tall hold down bolt.
great way to break a cast base plate..

cobalt327 I have an old 2" open spacer that I set carbs on top of to keep them from sitting on the throttle lever/linkage.

boothboy Actually I've rebuilt a lot of carburetors using a single bolt in a vice to support it with no problems. What ever it would take to brake off a lug from the base would probably do more damage to the rest of the carb in the process of braking off the lug. I went and bought a adjustable carb stand for rebuilds mainly because when I used the one bolt vice method what ever I dropped disappeared some place on the floor or under a bench or wherever. Using a stand on top of a clean shop rag is a much better solution. Things don't bounce as much on a soft surface.
