carbon deposits expelled from tailpipe

Caster56 · #1 (**permalink**) 03-20-2008, 12:16 PM

I just traded my 1971 Berlina for a black 1971 Spider, the Spider runs great, but has some difficulty starting, the choke cable only pulls out about 1/2 inch (is this normal?) also there is a black residue inside the tailpipe and when car is initially started from sitting overnite, this semi-

oily(has a slight gas smell) black residue is sprayed on the driveway, not a great amount and it quits after car is warmed, could this be a lean fuel mixture that I could correct by adjusting the cut-off solenoid, or could this be a harbinger of worse problems to come? Any help would be appreciated, Tom

You say cut-off solenoid so I assume it has Spica injection. If so, repeat after me - I will not mess around with the Spica system until I'm completly knowlegable with the operation of it which means I have read Wes Ingrams manual, and all of Roadtrips postings

I wouldn't be too concerned with the "dirtyness" of it at start-up, heck even mine does it

Thanks for the help, and No I will not fiddle with the SPICA, learned my lesson with that long ago, but I do know a mechanic who could do it if it needed it.

You may want to check your spark plugs for carbon to see if your Spica is adjusted too rich. Otherwise, yeah, the soot spitting is usually just from condensation in the exhaust as Osso stated.
