STILL running a little rich...??

[Soma576@xxxx]

List,

well i wound up getting my timing checked and my timing was off by 6 degrees. 
as soon as that was adjusted, my car has ceased idleing erratically when 
warm. now i have NO complaints with driveability!!! finally after 3 years 
everything seems to be working beautifully... the car starts up immediately 
every time, hot or cold, surges for about a minute or so when cold at 
leisurely cycle until it finds the 'sweet spot' and idles at around 750 
smooth as can be, and it doesn't fluctuate from that no matter how long i 
drive the car. 

my only complaints NOW are:
1. i'm barely getting 12 mpg in town (mostly on city streets, not much 
highway). i have a manual and i don't abuse it. any ideas? 
2. when i start the car cold in the morning and don't let it warm up, the car 
starts to sputter around 2500-3000 RPM no matter what gear you are in. this 
continues for only 2 or 3 blocks. extremely short lived problem, but happens 
almost every time. why?
3. when i start the car cold, it still smells kinda rich, but not nearly as 
bad as it did when the timing was off. is this normal or should i not be 
able to smell the exhaust? once the car is warm, the exhaust is almost 
non-existant.

as suggested in previous posts, i have checked all vacuum lines - good. 
throttle - good. three brass screws - seated. cold start valve does NOT 
leak when warm. vacuum is present at the proper places when hot/cold, and not 
present when it shouldn't be. timing? good now (set to factory specs). ALL 
ignition parts are about a year old.

here are a couple things to consider - i have a cat eliminator pipe, accell 
performance coil, K&N air filter. might make a difference?

the only thing i haven't done that i can think of is get the fuel/air mixture 
professionally checked. there are no shops in my area that have the 
equipment. is this the final task?

any other ideas are greatly appreciated. i'm getting very close to wrapping 
this up!

Andy
