Trying to get my 350 running again after 5 years

I have this 69 with a 350, have not driven it for 5 years. Turns out the distributor is bad, just replaced it, and the engine seems to want to run now, but could not get it started.

I don't think the engine is flooded, fuel is getting to the carb, maybe the level is not right yet, but should not effect the starting of the it. Tried to advance the timing slightly, not sure if that would help to make it easier to start, or should I go the other way. I had it set at close to TDC when installing the new distribute. Tried to use engine starting fluid as well, almost get it, but didn't keep going.

Any suggestions?

Re: Trying to get my 350 running again after 5 years

Try advancing a little more. I've gone through this myself when stabbing a new distributor, and usually you stab the dizzy at TDC, and then need to advance it quite a bit to get it to run initially. I am usually not advanced enough, and then eventually I finally figure it out, and it fires up no problem! I am often somewhat surprised by how much advance a small block chevy wants, especially if you have a performance engine with higher compression or have a cam in there.

Good luck!

The important thing here is that you ask me what kind of car I've got. "I've got a BITCHIN' CAMARO"

Re: Trying to get my 350 running again after 5 years

Pull the plugs and squirt WD40 or oil into cylinders and use starter to distribute oil.\
This lube will make the engine crank over easier.
Install plugs after they have been dried.
Externally charge battery.
Next day, crank up curb idle screw a couple turns.
Attach timing light and with assistant, crank engine.
Observe timing marks with light and rotate dist as needed for initial timing, whereever it might be, and engine will start.
Run engine for 20 minutes, then adjust initial timing, if stock camshaft, to say 8°-12° BTDC.
The engine will tell you what it likes, vacuum gauge will indicate a higher value when happy.

Re: Trying to get my 350 running again after 5 years

Finally, got it going, took about 5-6 tries. Will need to fine tune it, get the timing better, adjust the float and idle, bleed the breaks, then I will be ready to take it out for a spin. It‘s has been 5 years since I last drove it .

check the radiator level and power steering fluid for contamination and dump the oil too before you cruise after her long nap.

I'd make sure the carb is good. I just had an accelerator pump diaphragm let go and it pretty much flood the intake manifold. Rubber dries out over time.

Alan, I had the same problem on my car. Is the accelerator pump diapham easy to change out?

They are simple rebuilds.

Re: Trying to get my 350 running again after 5 years

well, what do you know, I spoke too soon. After got it going for about 10 minutes a few days ago, I didn't get around to it for a few days, but it won't start again. Have been trying, just won't fire up. Not sure why. Have tried to advance and retard the timing, went back and forth, still no luck.

I noticed I'm getting some sod build up on the carb, what does it mean? I wants to start, but at the last moment, it just goes puff, and smoke seem to spit out the carb.

Re: Trying to get my 350 running again after 5 years

I think your timing is off and your close to a back fire through the carb. But if you have been flopping the dizzy back and forth advance and retard you might have to reset to TDC and make the best possible stab at a spot where it will start and run again. Do you have any idea where the dizzy was pointed when it did start last? If so start there and once you get it started set the timing and lock it down before you shut down again.

What do you mean by

Black Carbon build-up?

Re: Trying to get my 350 running again after 5 years

I've stabbed a distributor wrong once when I put a top end on my engine. I swore up and down that I stabbed it right, absolutely could not get it to run for more than a few seconds, massive fireball through carb, couldn't get a timing light on it. My friend came over, literally yanked the distributor so far forward it yanked a plug wire off and started right up, it was at that point I ate my words and we re installed the distributor correctly. You've got everything, fuel, spark, I'm almost positive in your case it's the distributor. Advance it until the can hits the intake runner, I bet it will start, and then you know your distributor is stabbed incorrectly.

The only Mustang I'd ever own is a Fender.

Sorry, I meant "soot",

I will have to check the distributor, thought I had it on about right, it ran for 10 minutes fine, just had little hesitation when you rev it.

Re: Trying to get my 350 running again after 5 years

After 5 tried and could not get it going, I pulled the plugs, they were completed black. I checked them just a few days ago, and they were fine. So I bought a set a plugs and replaced it. That was 2 days ago.
I then set the timing to about 25 advanced, people tell me with my 12.5 compression and high cam, I should way advance it. I tried to start it again this morning, it puffed for a seconds, but did not keep going. Tried to crank it for 5 minutes, didn’t fire up. Left for about 2 hours, came back and tried it again, but still no go. Decided to pulled the plugs again, and they were completely black again. What would cause it? Timing too far advanced? Running too rich, oil leak( why would all 8 plugs be so black)

Re: Trying to get my 350 running again after 5 years

Plugs are sooty because of stationary running - not getting hot enough to burn off the soot. Try a hotter heat range.
Externally charge battery, squirt oil into cylinders, and do a compression check in order to find an idea of compression ratio. Any reading over 200 PSIG indicates high compression.
Yes, if engine has a long duration camshaft, it will need advanced timing.
Set initial timing for starting purposes, then plug in vacuum advance to full vacuum to bring in additional running timing.

Re: Trying to get my 350 running again after 5 years

Got it going. Had to take it to a old timer's garage. It was electrical, not enough voltage to the coil, only had 10V. Once he connected a 12V source to it, it started right away.

Made me feel stupid.
