My '70 w/ a Carter AFB keeps stalling. Here's what's happened. the other day, it would sputter as I slowed down, then hit gas, it's okay, but that kept repeating. Then it just stalled out, I turned key, but it would just crank, no start. Had to park on side of street. Went to try to see what's going on, I turned key, it started, but kind of rough, went a whole 25 ft, stalled again. I lowered fuel press reg to lowest setting, fiddled w/ carb primaries, it started, went about 150 ft. Still sputtered on slow downs, then stalled again. I fiddled with primaries again (opening them fully) and it started again, went 100 ft, stalled again, luckily right in front of a parking spot. I coasted into the spot. So, andybody got any clues? The carb had a total rebuild by a shop 6 months ago for emissions, and a new float, other is old one. Maybe flooding? Any help? Thanks.------------------

Brand new filter, less than 2 weeks old, but I'll double check, may have gotten clogged. Thanks. Any more ideas anybody?------------------

Try the air filter if its oiled or just so dirty it will do that and when you step on the gas it creates enough vacuum to draw in air to keep it running but letting off the trottle it wants to die or does..My friends 67 mustang started doing that on the freeway.when he let off the throtle to slow down it died he thought fuel filter or pump .I said no it would work opposite for that problem.and told him check his battery cables and air filter he laught at me and said yeah right..We stopped just off an off ramp at a gas staition and i said watch this pulled he air cleaner off and it started right away.put the cleaner on i died he said man i would have never thought it could do it that quickly..Bruce

if you have a vacuum advance take the distributor cap off and take the hose off the carb and suck in. if the arm inside the dist. doesnt hold the vacuum, replace the module. my advance was loose and would not hold a vacuum and was timed at 10' btdc. replaced the unit and it dropped my timming down to 4' btdc. re-timed to 8' btdc, now that vacuum snatches it from 8' to 10' with every stomp on the accelerator. my spark knock is gone and forgotten. i was so happy i went and got another tattoo.

Okay, well here's what I did. I checked out the vacuum advance the way Alex suggested a while ago. It's working, still moving. I had it running yesterday, it sat idling for about 5-7 minutes, no problem, didn't miss a beat. So it idles fine, but when it's got a load on it it craps out. What do y'all think?------------------

Got a spare carb you can swap to for a comparison test? You know what Alex says about those Jimmy Carter car-burritos. (and it's not the "no brag just fact" part either.)------------------

Unfortunatly I don't have another carb to swap. Living in AZ I don't have any of my parts in the shop, they're all in Cali. Yeah, I know, Carters are tractor carbs...  This carb will be removed in a while for a Holley Street Avenger 670.------------------

Gary I'm reaching here but have you checked TDC to make sure your timing didn't jump any.
And I'd pull the plugs make sure they all look good.Is the choke working good? and adjusted right? ------------------

I'll go yank the plugs and check them out when it cools down this evening (109 today). The choke is working good, open when it should, fully open.------------------

Okay, plugs look good. I started it up, it ran again for about 10 mins while I used a little portable air comp to fill a tire. It was running fine, in fact I moved it to a different parking spot, about 50 ft, and no probs. So what the heck is going on?  It starts okay, and ran fine, but I still don't trust it. ------------------

If you get stuck somewhere and it's cranking but not starting, try putting it in neutral, that always works for me. I've had my car die many times and have had to do that.

Sounds like to me it's vapor locking. Particularly since the weather has turned hot. Do you run the car with a insulator under the carb? If you don't, might want to give one a try. Then make absolutely sure the fuel line is not touching the engine. ------------------

Gary,
Have you recently run your gas tank really low or run out of gas? Especially on an older car with a gas tank that has not been recently cleaned/flushed, when you run it low you suck some of the accumulated crud from the bottom of the tank into the fuel line and ultimately into the filter. You said that the fuel filter was recently new, check it again. All symptoms sound like a fuel filter or possibly vapor lock.
Good Luck,
Gene (horseballz)

I'll check all those things out. Yes, new filter (Fram, see through), but I'll take a closer look at it, make sure no crap is in it. The tank hasn't been ran low on gas, I usually keep at least a 1/4 tank at all times. The carb doesn't have a spacer (no room under hood)...so maybe vapor lock. It has been hot lately (109). But I've always heard vapor lock doesn't happen on cars with elec fuel pumps, I have a Carter pump. It cranks and starts okay, no probs there. It started easy a couple of days after the first stall, but quit after about 2 mins of starting...aand it wasn't that hot out. I'll keep trying and report back. Thanks guys. ------------------

don't feel bad . my 95 mustang does that when it is really hot and humid. everything has been checked, scanned for codes and nothing shows up! it's really embarissing when you pull up to the line to race and it stalls. mine does it more when it is running lean. i usually take it out and romp on it and then it goes away for awhile. good luck!!

Yeah, I was thinking maybe I'll just take it out soon on one of the back roads and try it out, see what happens. Just gets me that it's been here for 3 AZ summers, and this is the first time it's had probs. Right now it's leading an easier life than before, getting only about 40 miles a month. Well, I'll try cruising it a bit this weekend.------------------
