Carb question

Ok, I as you may or may not know, I recently put on an Edelbrock Performer system on my 350. It has the 1406 carburetor. Now, my question is, when the truck's cold, it had good low end torque from idle. But when it's at running temperature, it kind of stumbles when I try to take off, espically when I put it under a little load like if I'm stopped on a little gradient. Is it adjustment probelms? Any feedback appreciated.

<font color="green"> Edelbrock's troubleshooting guide in the owner's manual is really gret for figuring this stuff out. Mine did the same thing, seems to me it was a bit lean at the low end, but it's been a couple of years. </font color>

Re: Carb question

I'm running a 1406 too, and the carb really has to be adjusted according to the book, and then you can go from there. I still have to adjust the choke, my high idle is really high [img]images/graemlins/grin.gif[/img] oops

Re: Carb question

Shouldn't have to, but if you have aftermarket heads, or the engine is a larger bore, etc. It is possible, not likely though. It's just a little choke adjustment for that screaming idle, I am lazy and it isn't that cold yet so not worried about it. All the important stuff really is just adjusting those screws in the front to the proper setting. I have a dwell meter that I use to help with the adjustment, can also use a tach for it. I believe the instructions say adjust one screw at a time, and put the screws at a place where they keep the engine running the fastest at slow idle. and then back off like a half turn or something. clockwise makes it richer.
hehe, same carb on 3 engines....no I've never done this before [img]images/graemlins/wink.gif[/img]

Re: Carb question

Sounds like she leans out when it warms up and the choke opens.....Try adjusting for max vacume per edelbrack instructions(the 2 screws in the front)or you can use rpm if you dont have a vaccume gauge(a tach in your truck isnt accurate enough, going to have to use a multimeter) You can download the instructions off edelbracks website
