autolite 1100 meant for automatic on a manual car

Was just doing some adjustments and tune up on my mustang after getting it out from winter.

Just bought a Shop manual and noticed the carb on my car is meant for a automatic transmission and not a manual.

Any idea if this has been hurting my performance?

anyone else running automatic carb on manual car?

thanks in advanced
 
IIRC they made one general 1100, the only thing that I believe is different is the gas pedal that has the kickdown rod for an automatic

There is a vacuum port for the automatic trans modulator. Maybe it went to the carb and maybe to the vacuum port block on the manifold. I can't remember. Otherwise, I believe they are the same. So when you hook it up, if there is an extra bung, plug it.
 
I thought one difference was the "choke pull off". An item that wuz put on all carbs @ factory and later thru 1 of the 1st ever TSB, directed the Ford mechanics to "pull it off every non-auto car that comes in for any type of servicing". I know it as the 'dash pot". There is a lill prt - looks like 2 pie plates placed face to face (Flyin saucer like), Has a plate, nut, plunger rod, boot, spring - "goesinta" the choke.
What do U C in the manual that draws ur attention (compared 2 ur actual carb)? Is it @ the bottom of the carb (Ludwig's point) or top - near that lill black 'bakelite' (plastic) circular thing (choke housing)?
 
Well funny story, I was driving it the other day and after accelerating it seemed like it was idling pretty high at a stop so i stuck my foot under the gas pedal and was able to pull it back up a little bit. It got better but still not back to normal idle. So as i was driving it home I was thinking probably my return spring connecting the accelerator arm to the exhaust manifold probably broke. I popped the hood and it was still there. Didn't have time to mess with it then so i finally got back to it today. When i started it, it was idling at 2,000 rpm right off the bat.

Started messing with the adjustments after pulling out the shop manual and noticed my carb matched the picture of the automatic carb. All this time I was wondering what the extra diaphram (dashpot) was for, Never really looked into it because it seemed to run good when i bolted the carb on. So i loosened the Dashpot Screw all the way out to see what would happen and it seems to be acting normal now.

I don't know if this is coincidence or not, just wanted to see if anyone else had an auto carb to work with on a manual and how they adjust the dashpot.

You bring up a good point on the linkage though that looks alot different too seeing as how the last autolite 1100 i had on the motor didnt have the autochoke or the dashpot. Might have to see if I can some how remove all the stuff involving the dashpot or plug it somehow.
 
"...see if I can some how remove..."
Mine's just w/o the plunger (rod that connects dash pot to choke). I "pulled (1/2 of it) off".

"...where i can find this TSB?"
Ford, I guess - never seen it, not a mechanic or Ford employee. It must be round 45 yrs. old tho.

Over the yrs. here, others have talked about these dash pots. They seem more knowledgeable that me.
I understand from some posts that there R carbs that have 2 of these things on them (& run fine w/both).
Not sure what that's all about. perhaps an ex - spirt will chime in.
Eventually a "sticky" might B produced (once some reliable info is established).

EDIT:
o0OOPPps - I got a '68 (I think that's the yr) Carter YF. Not the 1100 this post addresses. I'm uncertian which carb the Technical Service Bulletin may have been for but remember buddies grumbeling & "pulling them off" as I was a garage rat back then as well.
 
Howdy:

No problem in using an auto 1100 on a manual trans engine car. We actually look for them, for several reasons; there is generally less throttle shaft wear and there are more of them. Think about it. on a manual trans car the throttle is on and off with ever shift. With an auto trans it's just on. The only difference is the dash pot to control/slow throttle return on deceleration with an auto trans. Adjust it away and it's good to go. We tune auto trans cars so that they have the least amount of throttle lag on deceleration as possible. It sounds like you've got it figured out. Enjoy.

Adios, David
