Hello. My 1988 lh2.2 244 is giving me problems during cold starts. It takes about 10-15 seconds of cranking before it finally starts. Once it starts everything is fine and it idles nicely. It doesn't have this problem after the engine has been warmed up. I so far have only put in new plugs. The car often seems like it runs on the rich side so I wonder if it's some kind of fueling problem? Any ideas? Thank you.
