Ok, no start from the 72 today. I tried to chage the Optima that was in it, but no go. Picked up a new battery today, and put it in.
It just chug chug chug...nothing. Sometimes it will go slow, then it will slow downlike tis vapor locked.
I am getting fuel, I can see it being squirted from the jets.
Im gunna try to make sure im getting spark. Any tips on exactly where to look on an HEI set up?
Might do a refresh on plugs too. Wires are MSD, and should be in good shape.

al have someone crank the car while you have a spark plug wire off put a screw driver in the spark plug wire to touch the electrode and keep the screw drive less then a quarter of an inch away to a ground you will see the spark jump to the ground if you dont see a spark somethings wrong

how does it turn over by hand? check/clean connections?

Not sure if this is a technically correct way to do it, but take one of the spark plug boots off and put a new plug in it and rest the bare metal of the plug against the cylinder head and crank and have someone watch to see if the plug sparks. Only do it for a brief second to check. Maybe do it in a garage or lower light to see better.

Oh yea, another thing to do is check and see if the coil is getting signal. If you have a multi meter, pull the coil wire off the distributor and place the red lead on the coil connector on the distributor and the black lead on a good ground and have some one crank the motor and see what the reading is and make sure the distributor is sending the right signal to the coil.

so is it cranking too slow?

I think that's what he's saying.

Starter dragging making it seem like the battery is low??

BonzoHansen

ok, well, if it is slow, and he changed the battery, are the connections ok, grounds good, etc? did the timing change?

BigAls87Z28
03-25-2010, 09:48 PM
No timing change, connections to the leads are good.
Im gunna throw a set of plugs in it, see how that works.

Do you know if the starter solenoid is good?

BigAls87Z28
03-25-2010, 10:43 PM
Im assuming thats good. Its cheaper to replace plugs then a starter. Car seems to want to start, and the engine turns.

i dont see how plugs are going to help you here, if its cranking too slow...check and recheck all your grounds and connections

BonzoHansen

You run an auto pats store. Bring a starter home and try it.

BigAls87Z28
03-26-2010, 07:38 PM
Well, threw new plugs in it, and played with the timing. Now it just has a fast starting, but thats it. Still not starting.
Checked grounds again, still nothing. Ill have to get under it on Sunday.
Fuel is also shooting out of the carb here and there. When I pulled the plugs, they were black and coverd in fuel.

You should call someone who knows about cars.

Got spark?

BigAls87Z28
03-26-2010, 08:18 PM
Spark is a go. Checked that. I have consulted several people who know about cars...and then there are you asshats.
I have all 3 basics. Fuel, Air, and Spark. But no start.

BonzoHansen
03-26-2010, 08:24 PM
What did you do to your timing? Are you just randomly turning the dist? Was the distributor removed & replaced prior to all this? I can;t keep up with what you've done to that poor car.

You also need compression. Just throwing that in there with fuel air spark.

WildBillyT
03-26-2010, 08:44 PM
Two things:

1.) Before you try and start it make sure your battery is FULL. A weak battery can crank but not fire. Been there, done that.

2.) Keep a fire extinguisher handy just in case you load it with fuel.

What carb is on it? A Holley? Does it have a choke that may be stuck?

BigAls87Z28
03-26-2010, 09:25 PM
I pulled the Dist to replace the intake. Its possible that its 180* out, but even with it being 180, it should at least TRY to kick over. Ive done the 180* thing before on this car, and it started like crap and conked out. this is no start
Battery is brand new, checked and even charged off the shelf on weds.
You say poor car like I dropped a bomb in the damn thing.

Compression is the only thing left I could think of.

How old is the gas? Maybe you have water in the lines? You definitely have spark at the tip of the plugs?

BigAls87Z28
03-27-2010, 07:46 AM
Tank was dry so I just put in 5gal of fresh fuel in it.
I even added a water separator just in case. .

Sounds like distributor is out of place. You may need to crank it over to no 1 tdc and set the distributor and timing by the book. I've been out 180 and off by a tooth and the engine wouldn't start.

BigAls87Z28
03-29-2010, 05:39 PM
I think im 180 out. When i reinstalled the dist. I cranked the engine over to the marker, but that could mean Im 180 out still. Well, Ill have to wait for a free day to do it.

If thats it...anyone want a 72 Camaro?

pull #1 plug, bump it over to the compression stroke until the mark on the balancer it at 0 on the timing tab (TDC #1) drop in the diszy so the rotor is facing ftowards the #1 spark plug, drop on the cap and have the #1 plug wire facing straight forward. That should get you close enough on the timing to start.

If you're 180 out, then you might get some backfiring, bit if you 100-140 degrees out you may not get any type of backfire.

Sure, I can swap a nice LT1 in there that starts and what not. :mrgreen:

If you are working on it this weekend, lemme know I'll bring some beer or something.

Saturday I have to work, but after that, im gunna wrench.
Sunday is Easter...so that might or might not be a day to work on a car.
I wish it was clear tonight. Bastard rain.

Cool.
Im not sure what tomorrow will hold. Ive been talking to some of my contacts at GM, and they want me to come into the city tomorrow. I have to work, so they are gunna try to do something for tomorrow night. I dont think its gunna happen, but if it does...Im there!

BigAls87Z28
04-03-2010, 04:05 PM
Alright, Im gunna start on it today. If anyone wants to stop by and help me figure out the timing, good stuff.
Shoot me a text if you want to come back.

does it run? did jsfboa do work? ehh?

BigAls87Z28

got the timing marker to line up, pulled the dist, and dropped it back correctly.
Connected it all back up.
Checked for spark again.
Fuel spits upwards out of the carb. WTF.

transmaro93
04-04-2010, 06:34 PM
dude... something is wrong with the valve timing.. i was thinking about it last night.. only way for that gas to force upwards is if the intake valve is open on the upward stroke of hte piston... did you ever have that came or timing set out since the last time it ran... btw next time we gotta do it before 6pm... no light doesnt really help when working...

LTb1ow
04-04-2010, 06:40 PM
Did someone mention valve adjustment?!?

Oh oh pick meeee!

What is it doing?

sweetbmxrider
04-04-2010, 06:55 PM
clogged carb? flooded?

LTb1ow
04-04-2010, 06:56 PM
Bad gas?

JL8Jeff
04-04-2010, 07:23 PM
Gas spitting out sounds like a sunk float in the carb. Probably need to pull the carb and clean it out good and check the needle and seat for debris flooding it out. And check the float to make sure it's not full of fuel.

BigAls87Z28
04-04-2010, 07:34 PM
Will do Jeff.
Gas is fresh...as already been said
Nothing should ahve changed reguarding cam timing. Only thing that is different from the last time it started is a new intake.

BTW, its an Ede 600CFM w/ electric choke. Gunna have to tear down the carb I guess...bah

transmaro93
04-04-2010, 08:22 PM
yea im part of the new age and dont know much about carbs.... but that was an awful lot of gas shooting upwards out of the carb... almost like the exhaust was completely blocked off and the gas had no where else to shoot but up back through the carb.... its deff a weird one to say the least...

maroman88
04-09-2010, 09:26 PM
i had the gas shooting up like that wen i did the carb swap.... needed a new float

BigAls87Z28
04-18-2010, 05:57 PM
Ok it runs! Like a champ too. It was another 180* off. We dropped it down and started right up without fuss. And it runs much smoother then it ever has. I was impressed actually.
Thanks to Brandon for helping me out.

transmaro93
04-18-2010, 07:13 PM
yea man for the actual 10 minutes of work it took to get it started... that thing runs nice... now everybody is curious to see if you actually part ways with it now.... hahah

BigAls87Z28
04-18-2010, 10:31 PM
Yeah well we will see. I still feel bad I have to part with it, but its almost a must.
Gunna have to do an oil change on her soon.

I think everybody has to do the out 180 with the distributor at least once in their life! :lol: Good to hear it's back up and running.

Yeah, really. I did it with the distributor right and the plug wires 180* off from my markings. That's where the real talent comes in :mrgreen:
