'66 Help

So I've had my 1966 mustang for about a month now and mostly everything is original and has not been changed or added. When I drive and I stop at a red light it dies and won't start up for a minute or two. This does not happen every time I stop but about every other day. I know there could be several things that can make this happen but what are some things I should look at first. I just replaced the fuel pump thinking that was it but that did not solve the issue.

Does anyone think it could be the carburetor?? I'm not sure the last time it was cleaned.

It doesn't hurt to clean it just give it a go

That carb is really easy to rebuild and if you get the float set correctly it will probably fix it.

Float is a good start and so are vaccum lines. Cover the top of the intake with your hand or a towel. If it dies that's good if not there is a vaccum leak. You can also spray carb cleaner or starter fluid around the carb to see if the linkage is worn and taking in air. Change any old fuel filters. Usually one by the carb one in the mechanical If it has one and one on the gas tank. If that doesn't work to make sure it's getting fuel start the car and if you undo the fuel feed on the carb it should be coming out at a good rate if not it may be plugged up somewhere. Goodluck

Thanks
I adjusted the carb so it idles higher. I have had no problems since, maybe that small adjustment fixed the problem. I will also check the vacuum lines for any leaks.

What is it idling at? Is it auto or manual?

Re: '66 Help

Since your idle is high. I would keep an eye on your plugs. If they aren't burning/wearing correctly, there may be another problem. I have had that issue with my 66. I found that depending on the carb you have on can make a difference. It could be touchy or it could be the difference in the weather depending on the atmosphere pressure that day.
