I own an 85 f250 4x4 with a 460 and C6. I put an edelbrock performer 460 intake manifold, an Edelbrock 750 CFM carb, an MSD ignition coil, replaced starter, and did a full tune up. I was thinking that all this should make my truck start on the first turn of the key, but it takes three times at least. Any ideas?

Just putting a carb on won't make it start &/or run right - you have to do a LOT of adjusting and maintaining.

If you want to be able to just put it on & drive, put EFI on.

 

I have a 460 with an edel 750 cfm performer on her and if you put an electric choke kit on it..it should fire right up on the first try.
They cost bout 60-605 bucks and are well worth the trouble.
Fairly easy to install, and all you have to do when startin is push the throttle down once realy quik and it will fire right up.

I have a similar setup on my 460. Before I try to start it I pump the gas about 10 times, then push it to the floor one last time and let it up about 3/4 of the way (so that you are giving it 1/4 throttle) then crank it over. As soon as it fires you will have to play with the gas to keep it running. I use this technique in below zero weather and it still works. By the way, when I do this I don't even mess with the choke.

 

It came with an electric choke on it and that's not when i have problems. It's when it gets to normal operating temp then I let it sit for a couple of hours just enough so that I don't need to turn the choke on. Also the carb is very well tuned; I tuned it myself and then took it to a mechanic, twice. So it better not need tuning.

Im not sure about this on yours..but i had a similar problem with mine once..it turned ou to be the choke was sticking for one reason r another ..cant remember exactly why tho.
Sorry i couldnt be too much of help on this one.

much more to come!!!

 

well it doesn't act like it's the choke sticking, it acts like it gets flooded cause if i slam my brakes down htne my truck quits, and it blows just a lil bit of blue smoke.

just sent you a private message fishman..go ahead and pm me back thatl be much quiker than goin through the board here

 

forgett the pm thing lol..your guess is as good as mine..but was it doin this before you put on the new components?..if so may be something with your ignition timeing..i've heard that msd components are verry fussy when not put with an all msd component system.

Well, it ain't the timing. It's almost like I the float level is not set high enough because I have to give it gas to crank. Is there any other way other than messing with the float level to be able to give it more gas? It is just kind of embarresing that I have this nice looking truck and she will hardly crank, or so it seems.

couple things seem strange...
If you have problems with the truck quitting with brakes on, it is fuel, and I am not sure why you would not try to adjust the float level. If I remember it is pretty easy on the Edelbrock.

You mentioned "turning the choke on". ????

If you have an electric choke, it is automatic. Don't think that your engine does not use the choke after it has been driven. If the engine cools down much at all, the electric choke will give you some choke to start.

You also said that it seems like it is flooding, but then you want to give it more gas.????

Don't be so quick to assume that it is not timing. You mention that you need to give it gas to crank.???? The amount of gas will not effect the cranking ability of the starter. If the engine is having a hard time turning over when the enigne is warm, and then pings when you get on the gas, it is definately the timing too far advanced. Retard the timing untill the pinging goes away and see what happens. Don't even worry about a timing light to do this, just try it.

My 460 with the 1411 (750cfm, electric choke) starts immediately even after the truck has sat for weeks.

You have another post on a pinging problem. This could be too much advance in your timing, bad fuel, wrong grade of fuel and even a faulty thermostat. I would assume if I were you that the two problems are related.

I would start with checking the choke operation and wiring, retard the timing, and adjust the float level.

 

I will try all these things, I really appreciate all the info. anything else just pm me or post another message. thanx

Adding to an old one here because I have a similar situation...

I am using the 750cfm edelbrock/electric choke on my 460 and have a little more trouble than I think I should starting after the truck is warmed up. I also have the edelbrock Performer cam (installed straight up)/intake, MSD6A ignition, and headers. No air pump.

When the engine is cold, blam, starts great. If I've been driving until the engine is hot, turn it off, then within a minute or two start it up, bam, starts great. BUT, if I drive it until it is warm and then go into the store for like 20 minutes and come out it is a bit of a pain to get started, takes 5+ seconds of cranking and some gas. Purs like a kitten once started though.

Am I being picky or should it just fire right up no matter the conditions? I am currently running at 8 degrees BTDC. I was getting a little pinging when accelerating and believe the electric choke version of 750cfm carb comes pretty lean so I put in one stage richer rods/jets. The new mixture relieved quite a bit of the pinging but didn't seem to make any difference on the warm starting issue. Retarding my timing below 8 degrees struck me as odd but maybe I need more? I've read that some ignition systems retard timing while cranking and don't believe my MSD does this, could this lack of retardation on cranking cause this problem?

The only other thing that is maybe odd with my truck is I get a lot of loud popping out the exhaust when decelerating (its a manual). I've got dual exhaust with glass packs so this might be normal but I don't have any buddies with trucks to compare to. Is this popping normal or a symptom of an idle mixture problem or something? I've sent the carb idle mixture based on the manual (highest rpm).

 

the popping in your exhaust generally indicates a rich idle condition. your edelbrock manual tells your how to set it, i can't remember how.
