Got 85 AMC Eagle with 258 an auto trans & it wont start. It ran fine before but had small valve cover leak guy who fixed it used hardware screws instead of automotive bolts for the valve cover. He tightened them down they were correct size but phillips screws & he used RTV organge stuff to seal gaskets an stuff with on it. It drove fine afterwards but had real slight smell of something hot. Drove it home & went to start it next day an will turn over but not start. Any Ideas?

Start with the basics, does it have fuel, spark, timing, and air?

Yes the basics first. That hot smell could of been the new valve cover gasket setting in

I checked it an nothing pinched or loose that I can see. The hot smell could have just been were it was getting low on antifreeze again it goes through 1/2 a jug in less than 2 weeks. Was told I have I have a air bubble in it somewere but nobody knows how to get it out. I check the ignition coil & starter everything is connected. Was was wanting to know could a loose vacuum line cause it not to start? When he took the valve cover off an put it back on he just slipped it under everything he did not disconnect nothing said his way of slipping it under was easier since he he had no idea were things went. An he knocked a couple vacuum lines off doing it an he put those back. Just wondering if more of them came loose an caused it not to start? It ran fine the day before it would not start I took it to work an home no problem. The timing is set just a hair high on it were the carb needs swapped out to the Motorcraft 2100 series carb. Cant find anybody here that knows what needs done to swap the carbs out from Carter bio feed back to Motorcraft 2100 series. Most people around here dont know AMC & ones that I found that say they do have no clue when it comes to all the vacuum lines on it.

There is a vac connection on top of the intake by the firewall that can come undone easily. Alot of the vac lines that sit on the bracket ontop of the valve cover are emission related. If thats no concern then just make sure you have the one going from the disty to the ported vac switch and the one at the back of the intake goes to cruise control, t-case, heater core valves and vac gauge. The rest you should follow to the pulse air valves, vapor canister, intake heat valving and such.

The carb swap is pretty easily done actually, especially if you don't have the electronic carter. You'll just need an adapter to fit the motorcraft carb to the intake and maybe make a throttle spring bracket. The ebay seller gronk makes a good swap kit. I wouldn't get his tfi kit because the coil he sends is meant to be fender mounted in a cj, just get the petronix coil.

Basically if you go a non emissions carb swap, this is what can come out, although you might not even have half of this already.

ok but can a vacuum line cause it not to start?

Not usually, a vac line unhooked can cause a start to stall condition, if it were a large vac line such as a pcv, or brake booster line.
Check for spark.
Going through coolant? It has to be going somewhere, if not on the ground, then either in your engine (crankcase/combustion chamber), or in your hvac box. Air pockets don't eat coolant, they can cause overheating or lack of heat but that's about it. They usually will work themselves out fairly quickly on these old inlines anyway. Check your plugs to make sure they're not fouled.

My wagon wouldn't release the air bubble (found out I had a bad thermostat from a batch of them) so I loosened the temp sender to burp it and it's been fine since. Pull the dist cap off and check for corrosion or moisture killing the spark. If I was visiting the wife's family I could help in person (they are all over Scott county and near Gate city)
The connector on the ignition coil may have been knocked loose when he did the valve cover. The horseshoe design is a total POS.

ok will check all of that this weekend. An yea on the coolant I can fill it up to the top of the jug an run it for about a week an it will be at were it says add. Could it have something to do were the car sat 8 years before I got it then did the tune up an started driving it. Could there have been something that has been overlooked that could be causing it to use this coolant?

Use a mirror to look at the bottom of the waterpump and check the weep hole for rust stains that mean it's leaking. Check freeze plugs for rusty stains too. See if the floor on the passenger's side is wet.
