She's up an Running!

[jsevern]

Hey all,

I just wanted to let you all know that I had great success today. I posted earlier about some carburetor issues that I have been having. I picked up the new carb, installed it, siphoned that gas out of the tank, put new gas in, and then turned the key. She fired up!!!! I actually drove her around the block today. It was an exciting day! Thanks for all of your help. Now I need to read up on timing and carburetor adjustments. I'll post pics as soon. I'd like to get the Stang all cleaned up first. I have to wait for nicer weather. Do any of you have any quick tips on carb adjustments? Idle, fuel/air mix. Everything is stock on the car.

JS

congrats .I know that feeling and it's great .here are some tech tips from classic inlines for tuning the carb and timing with a vacuum gauge which in my opinion is the best way.http://www.classicinlines.com/Vacuum.asp. you can get a gauge at any auto parts store for about $25.00. or you can adjust the idle mixture screw all the way in lightly seating it ( too tight can damage the needle and seat ) then out 2 to 2 1/2 turns , start the engine then adjust the screw slowly out till the engine starts to run rough then back in untill it runs rough again the center between those 2 points should get you where you need to be also make sure to set the idle and check to make sure the choke is open before you start, the Idle and timing specs are also in the tech section on the Classic Inlines site.

Congrats. It's always a good day when you get a car back up and running after a long down time.

What quickersix said is a good starting point. Not much else you can do with a stock carb or ignition.

The first thing you do to tune a carb is to make sure the dizzy is correct. Rought idle and hesitation can be caused by botht he dizzy and carb. You'll drive yourself batty dorking around with the carb with no change if the dizzy isn't right. SO...make sure the intial timing is correct/where you want it, and if still running points make sure the dwell is correct. Also check the advance and make sure its functional.

After all the dizzy stuff is set then fiddle with the carb. The idle enrichment/mixture screws will affect the idle speed when you start to adjust them. I typically do three iterations between the idle set screw and the enrichment screw. I start with the mixtrure screw and adjust it for max vacuum (so you'll need a vacuum gauge) then change the idle speed screw (you'll need a tach for that). Then go back to the idle mixture screw and readjust that for max vacuum. And reset the speed. And then do it one more time! After that it should be all set.

Make sure the choke will open 100% after the car runs for a while.

Also make sure the throttle will open 100% (90 degrees) whenthe pedal is "mashed" to the floor. I went from a 1940 carb to a 1100 carb and thought the throttle linkage didn't need adjusting. But I found out that the 1100 was only opening up 3/4 way. You'll need a helper or a way to press the gas pedal to the floor and then look down the throat of the carb. Don't assume it is opening the whole way, you MUST lookdown the carb.

Lastly check the unloader function of the carb. It does help if the engine is ever flooded.
