hard start

["Jonas P" <Delorean3543@xxxx>]

About a week ago my 1981, auto tranny, vin 3543, with 23,000 miles 
developed a hard start problem when when the engine is cold. It is 
taking as long 3 to 5 minuntes to get her going. Its then takes about 
2 minuntes of warming up befor it is ready to run well. I got this 
car about a year ago after the last owner let it sit for 10 years,(so 
I was told) at that time it had 12,000 miles, this is my daily 
driver. After alot of parts and updates it had the same hard start 
problem it has now. How ever it seemed to "fix its self" so to speak 
after 5 or 6 weeks. Well its back again, a motor head friend of mine 
thinks it is a problem with the mixture and that it is running rich. 
Any input on how to fix this would be great, Thanks in advance
