i have a edlebrock 600 cfm i was getting bog down on quick takeoffs, i noticed on i think its the accelerator pump,the part thats on side has 3 adjustable holes that looks like adjustments to put either get longer stroke or shorter stroke, it was in middle hole i put in lowest of 3 holes what will i get by doing that more gas going into carb or what. it is a 360 with cam and headers and edlebrock intake and about 360 HP will this help or hurt my bog down at fast takeoffs other than that car runs like top? thanks
 
If you moved the rod to the outer hole, you have less pump shot. Inner hole is more shot. BUT you do need to make sure the height of the pump plunger is correct after you change the setting (it will change slightly and you must bend the rod to compensate).

See what difference it makes if any. If less shot helps, you are too rich, or your ignition system cant handle it. If more shot helps, you are lean, either leave it there or go up a setting on your main jets. If you do not notice a difference, the carb is not the problem, put it back and look at the ignition system. (Yes I keep mentioning the ignition system, but 90% of carb problems are ignition related)
 
how do i check, and if off how do i fix, not much at carbs just was told thats what i should do and is bottom hole what you call is inner hole and by more shot you mean more gas right? thanks also if i dont adjust what will i hurt. i am running pertronix ingitor 2 with flamethrower coil thanks so much
 
Did you get the carb new? If not, go to the Edelbrock.com web site and download instructions for the carb. It will also give the measurements to the critical areas.

The arm to the lever for the accelerator pump (Thingy with 3 holes) should be moved closer to the carb. AKA inner hole/slot. Also described like; The hole closest to the carb, rear of engine, closer to the main body of the carb, hole nearest the carb or fulcrum/pivot point of the arm. A million ways to say the same thing. (Damn you english languageer guage no wait...nevermind. He he he)

Yes, more shot means more gas.

The rocking arms end that sits over the carbs top plate has a measurement. Off hand I can not remember it. You can adjust the height of the arm by bending the rod that attachs it.

Make one adjustment at a time. Road test the car each time in about the same manor and temp etc... to compare it to the last test.
Also remember that Edel./Carter also has different size clusters or shooters. Those are the little things where the gas gets squirted out from when you pump the gas. You know you can see them in action when the engine is off and you hand crank the carbs lever for gas. The squirters came in 3 different sizes in a package deal where you get all 3 in a package.

I just proof read this and I just ramble a bit. Sorry bout that. lil'tired.
 
actually, the first change is metering rods, not jets. look in the booklet for the condition that necessitates the change. you can get the kit for around $40.

Click to expand...

As mentioned,go to the website for there calibration referance chart.
A calibration kit will be necessary as well.Sounds like you are way lean,either a metering rod change,or metering rod/jet change is necessary.Either way without a calibration kit you wont be able to dial it in correctly.

Personally,I think you are under carbed for your cammed up 360.Most guys on the site seem to be running a 750.
 
He just didn't mention cam size or anything else about the engine.

Cam size, intake, compression, heads...stock ported, etc.... A 600 could be just right, or a bit small.
 
the main problem that i get with ALL eddy carbs is that the floats are always out of whack. the float drop is supposed to be 15/16" to 1", and its always 1 1/4" to 1 3/8" and that makes a big difference. i have put on so many this year and not one has been correct out of the box. pop the top airhorn off and reset the float drop and float level(7/16").
 
have never adjusted float before could you go into little more detail on how to do it? thanks
 
It's in the instructions. Basicly, your bending the metal arm the float hands of and the rest stop on the other end of the arm. The measurement is taken from the bottom of the float to the air horn base. This is done inverted aka upsidedown, so the bottom of the float becomes the top and measured to the (Now) floor of the carb cover (top of carb) the side that mates to the base/main body of the carb.

Read instructions for best results. Trust me.
