running rich??

["honda250r1989" <sky250r@xxxx>]

I have an 83' dmc w/ 19k miles.
I tried to start it this spring and it would not fire.
After replacing the coil and cleaning some connections, it fired up.
But now it runs like the fuel line goes strait to the intake,extremly 
rich with large amount of white/ brownish smoke rolling out the 
exhaust, with a clear and black gas smelling liquid leaking out the 
exhaust. 
I got it to start a few times like this and it runs smooth at above 
3000 rpm or so, but the lower the rpm the worse it runs, needless to 
say it won't come near an idle.
I'm gussing this problem has some thing to do with the fuel pres. 
reg. but I am hoping to hear from some one that knows more about 
deloreans than I do.
Thank Ryan
