So now that I have my 1.7L with D-jet running I need to do some fine tuning. It's getting pretty cool here now and the last couple of times I have started the engine it has been around 45 deg F and I have to constantly maintain the throttle to keep the engine running. it does start right up though. Shouldn't something keep the rpms up with a rich mixture. I did a some looking on B. Anders D-jet site but didn't really find an answer. AAR? cold start inj? intake air temp sensor?

The AAR is primarily responsible for cold start enrichment. The cold start valve doesn't kick in until the temp is below freezing -- then it only squirts while cranking. The AARs have a tendency to freeze up (rust) over the years. Most of them can be fixed by spraying some rust penetrating oil into them.
