I need your help tuning my autolite 1100. What i was going off of was the sound of the roughness going away but clearly i am an idiot. What specs are there for the autolite 1100 as far as the idle air mixture screw is concerned

First the carb adjustments is the very last step of a good tune up done in this order. You did state a 1967 year and the car model as a Mustang, I am guessing it is all stock or does it have some mods? So some of the base timing settings will be general info. Also assumes that the engine is in good operating condistion all cylinders are equal compression within about 10% of each other. No matter what the carb adjustment though will still be correct with exception of maybe the curb idle RPM specs.
With a stock point type system
1. Spark Plugs are gapped at .034
2. Point gap is set at .024 to .026 for the base generic setting you would want a end up with Dwell setting of 36 Degrees for best results.
With an electronic system it will be different one example.
1. Spark plug gap for a DSII is .044
2. There is no dewel setting
3. Factory Base timing is set to aprox. 6 BTDC for manual trans or 12 degrees BTDC for an auto trans. I usally set these to 8 to 12 degrees depending on locale condistions. If your car happens to have Calif emissions that changes some of the settings too.
4. With the engine now warmed up to operating temp and the choke fully open. Set idle mixture to lean best idle. This done by setting to the highest Idle RPM using a Tach / Dwell meter and you then would turn the mixture screw in a 1/4 turn (leaner).
5. Last set the Curb idle to 500 to 575 RPM for manual trans, 550 to 600 RPM for auto trans in drive with parking brake set, this will usually be 50 to 100 RPM higher when trans is in Neutral or Park.
The order of the settings can make a differance to the final tune this is why the carb settings are last thing. Are you confident that your carb is in good condition and with the float level is set correctly? Hope that is of some help. Good luck

Whenever i turn hard right the car cuts off and only makign a right. Please help!

Thestang- For the die on hard right turns- I'd suggest that you start by checking the float level (As Bubba suggested), float armature (making sure that it can swing freely).
Does the engine die or just lose power? Has it always done this or is this something new?
Adios, David
Econoline":25m49ybr said:The rule of thumb is when you pull the top of the carb off and flip it over, the float as it rests on the needle and seat should be level/parallel with the gasket surface of the carb top. If when you do that the float is high(upside down) you are running the bowl lean, if it's 'low' you are running it rich with a chance of flooding. Also be very carefull when tightening the screws that hold the carb top on. 1100's are notorious for warped tops b/c of over tightening the screws.

About 6 screws remove the top of the carb, flit it over, Measure 1 & 3/32 in frm gasket surface to top of float. Bend tab as appropreate to achieve this.
