Won't go past 20 mph

[eat_more_drift]

Like the title describes, my Datsun 510 started acting up on me. I'm writing on here hoping to get some feedback from anyone

as to why this might be happening at steps to fix the problem.

 

So, these are the symptoms:

Car was driving fine then out of the blue the car started to sputter and didn't want to go past 20 mph.

It doesnt die and it starts up still but when I give it gas, it starts popping from the exhaust and doesn't want to rev anymore. But it doesn't die, it just

keeps popping if I keep my foot on the gas.

I changed the distributor a couple of months ago before this started it that's any help.

Since the problem, i've changed the spark plugs and fuel filter but still no luck.

Please help!!

Ignition Condenser?

 

You are still running points?

[eat_more_drift]

Idk what I'm running, but I'm pretty sure everything is stock under the hood.

[Laecaon]

Well if you are running the stock ignition points ignition, I would see about changing the ignition condenser. It can cause some serious lack of power. Also make sure your distributor is timed right, but by the sounds of it, nothings has really changed.

[eat_more_drift]

It wouldn't be the carburetor? Or something to do with the gas? Maybe the fuel pump?

[Laecaon]

It could, You can check your fuel filter to see it looks dirty.

 

Fuel/Air ratio and ignition timing can cause backfiring.

 

To me the ignition condenser to very likely to go out (more so than any carb related thing) They can be bad out of the box. Its cheap ($3)

 

To me you havent changed anything in your car. This problem develops. If nothing is broken then it is something that wore down. In the ignition circuit that is usually the points or the condenser. In fuel delivery, lines or fuel filters can be clogged, fuel pump can wear down (not high enough output).

 

SO make sure you have consistent spark, and make sure your fuel delivery is constant and strong.

Alright, I'll change the ignition condenser tomorrow and let you know how it went. Thanks a lot.

It sounds like maybe your girl freind is too fat.

Jk man good luck id say dizzy, or carb or both, maybe fuel supply.

sounds alot like what my truck was doing with i first got it, ended up being the carb. the float was toast.

Next time it acts up as quick as you can shove in the clutch and turn the ignition off. I mean as fast as you can and then pull over safely, so have a care on the highway. Now take the air filter off and look at the glass on the front of the carb. Is the fuel level on or close to the line etched into the glass? If it is it's not your fuel pump or fuel supply to the carb. If the level is low or not showing see the bottom line*

Backfire out the exhaust is usually an interruption in the ignition circuit and can likely be badly set up or worn set of points. If the points do not make good contact or contact is lost briefly the unburned gas and air goes down the exhaust pipe. As soon as the ignition begins working it exploded the fuel/air in the pipes. A loose wire to the ballast resister, to either coil terminals or at the points themselves will do the same.

 

*If you have never changed the fuel filter ... do so. $7 and a screwdriver.

I find it funny how they ask questions regarding problems when they don't even know what they even have in the car.

[datzenmike]

At least he knows enough to post an oic of his ride. +1

 

Drift attempt stirs up bowl sediment that blocks jet.

Rust drifting down the line from the tank will also cause intermittent blockages.

cool car

However take a photo of what you have.

Motor carb and disributor and coil area.

 

 

Most times you young guys swap out to HIPO coils and it fucks up the system burning somethin up.

 

stock is FINE.

 

but lets see soem photos
