Edelbrock 1406 Idles Rough On Cold Start
Posted: Mon Jan 09, 2012 2:27 pm
I adjusted my timing a bit and got it tuned in. I did this with the engine warmed up and I removed the vacuum advance like the book says. Took it for a drive and the motor sounds smooth. I actually had to turn the heater off to here the engine. That's a big big improvement. Tweaking my timing got rid of all the shaking I was feeling. I took it out on the big road and was doing 65 with 1/8 less gas pedal.
Now….I let the engine cool for several hours then I started the engine again and it idles rough until it warms up. Lots of chugging. I had to keep the engine running with the gas pedal for about 20-30 seconds. Finally it wanted to idle on it’s own (Roughly Though).
I let the engine warm up to good running temperature and it smoothed out and is running smooth and quiet again. What adjustments can I make to improve a rough idle on cold start-up? It’s an edelbrock 1406 w/ electric choke.
