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

In this pic I used a valve cover tall hold down bolt.

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.

Totally uncalled for, kidding or not. No more, please! I've received a few complaints on this post.

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.

Every time I have the carb off I adjust the idle screw, getting those little
slots in the bore just right.
But when I adjust the carb on the car that setting gets invariably lost.
So today I took the carb off sat it on the stand and set the idle screw to just touching, like this.


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.

Generally when setting up pretty much any carb, whether it's on your car or lawn mower you can pre set your idle mixture screws to 1-1 1/2 turns and the same with your idle speed adjusting screw. That usually will allow you to start your engine . Then after warm up you can fine tune it with your tachometer. That being said there is nothing wrong with counting turns from original 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.

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.
