Re: cold start sluggishness
Yeah - that is what I was thinking on the whistle. I will check all
the temp controlled vacuum lines and switches first. They may be two separate problems that happen to coincide. I guess the reason I figured my choke wasn't the culprit is that at idle it runs perfectly throughout the warmup period and the bogging doesn't start happening until the whistle begins and then goes away when the whistling becomes quieter again at operating temperature.
