Ok, I've gotten my carb cleaned out and adjusted somewhat close, replaced points and condensor, distributor cap and rotor, plugs and wires and also adjust my timing. I was having a problem with some light throttle surging and some hesitation while accelerating, which this mostly fixed. Now, my car runs great for around 20 minutes but once everything gets hot, I notice that the car tries to hesitate some when accelerating. I can get her to normal operating temps and everything is fine...but give everything else time to heat up under the hood and that's when I'm noticing the problem. I did notice that my ignition coil is getting really hot (it's the stock coil that's located on the intake manifold). I may need to double check the gap on my plugs, just in case. Any help would be greatly appreciated!
Choke isn't sticking and just got done checking plug gaps (all are at 0.035"). Brings me back to possibly the coil or maybe the condensor. Thoughts? Troubleshooting advice?
there is a good chance the coil is over heating. it would be a good opertunity to switch to an eletronic ignition system like a pertronics or a duraspark.
Coolvettes: It's a 1971 Maverick with the 302 V8, stock ignition (points) and the original ignition coil.
Bryant: I'm looking into getting a Pertronix Ignitor III and Flamethrower coil at some point, but for now I just need the car to run without me having to spend any money hoping to find the fix. Basically, the wife has me on a tight budget and I need to know exactly what to replace before I go and throw any money at the car.
you measure the resistance of the winding in the coil. i dont have the specs but you should be able to look them up. also did you check the dwell of the new points? is the fuel line going near the exhaust?
Bryant: I'm not sure about the fuel line. The exhaust is the stock, single line exhaust/muffler on the passenger side....so I'd guess that it isn't near the fuel line which appears to come from the driver's side. mashori: The carb is the stock Autolite 2100 2bbl.
Update: Car ran even worse on the way home in 106 degree heat. Tried adjusting the carb to both leaner and then richer settings from where I was with worse performance both ways. Put carb back to where it was. I don't know if the dwell is set correctly but the points gap is set right. Would this even be affected by the motor getting hot? I'm still leaning towards the coil, but still not sure.
heat driectly effects the ignition coil. if you dont have the ability to test it then you can try replacing.
I know it's not cheap but worth the money Pertronix II And your coil. Maybe you can test the coil first and see if it's functioning or not like bryant said.
Amazon has the [ame="http://www.amazon.com/PerTronix-91281-Ignitor-Adaptive-Cylinder/dp/B000JUT7RS/ref=sr_1_1?ie=UTF8&qid=1312409291&sr=8-1"]pertronix II[/ame] for $97
Anyone know if there's a huge advantage to having the Ignitor II vs. the Ignitor III? I know the III has the RPM limiter and multi-spark, but is it worth the extra $$?
I would check the coil with a spark tester if you don't want to just replace it, but it sure sounds like a symptom of an overheating coil. The spark tester could cost as much as the coil. I would do the petronix as well, but a bad coil with a petronix is still going to cause problems.
If the dwell wasn't set correctly, but the points gap is very close (0.016 ±0.001), could I still get these same symptoms?
