E4ME carb settings

[justacruzr2]

Is there a web page that has the settings for the E4ME carb? There are 3 things that need to be set after a rebuild. One is the TPS which I think is .5 volts, the Idle Air which I think is 35 degree dwell and 1 other that I can't remember right now. Appreciate it. Will be doing the engine swap in 2 weeks after which it will get painted and after 5 summers of resto work it will be done and ready to go. Can't wait! Will post some pictures of it later.

The specs I had were in a book that is currently packed in a box somewhere...

BUT

Hopefully you don't mind us tagging another member here who needs the exact same info you do for the motor he has about to go in:

There's a lot of E4ME settings.

Need to know year, carb number, engine, make and model.

Got a Delco TuneUp book here but there's a ton of specs in it. Help me narrow it down.

It is not just those settings. There are several that need special tools to set while the carb is apart. The adjustment plug on the TPS can be tricky to remove if you do not know how. One wrong move can ruin the carb

have you already rebuilt the carb? or are you not going to do that?

1.304"
1.756" on bench, final adjustment on vehicle.

There are more.

I knew you'd be excited about the info, not THAT happy, but still.

Been away this past weekend so to answer all your questions here we go. Don't mind waiting a little bit. Engine is coming out of the car it's currently in next week. Carb will be rebuilt at that time. It's been rebuilt before so all plugs are out. Have all the special tools to do the job. I've rebuilt it twice before. Carb number is 17081201, year is 1984, engine is 305. Thanks.

That carb is older than 1984. The year is 1 meaning 1981, with code 201 which doesn't mean much. The only thing you HAVE to worry about using that carb number for is the rebuild kit. Ironically, the FIRST carb on the E4ME listing is a 17081202. Doesn't even show a 201.

Anyway, assuming it's an 84 system setup it will live in, the carb that you SHOULD be using most likely is 17084201. With the 4 for the 1984 model year. Still a 305 H, but if it's in a 1984 car, you are running the 1984 system, so it's probably best to set the carb up for the car, not the original settings for a 1981.

Obviously, the primary lean stop will be set with the tool gauge at 1.304"

The IAB valve initially gets set at 1.756" with the Shepard's hook tool, and then once on the car, you do the final adjustments with the dwell meter.

Carb screw minimum idle speed is 475 in drive, ISC solenoid max is 750 in drive.

Rich stop is set where max travel of the M/C solenoid paddle is 4/32" (why can't they ever say 1/8"??? Probably because of the little scale on the measuring tools) This is of course, +/- 1/32" so take that into account as well.

The TPS is set at 0.48V at curb idle.

Vaccuum break angle is 27 degrees of choke blade angle when fully retracted.

Mixture needles are set at 3- 3/32 turns CCW. (Interestingly, all other 84 E4ME carbs start out at either 3 or 3-3/8 turns CCW.)
As with anything else, it's a 4 point adjustment carb, so the mixture screws and IAB settings are starting points.
