I have a 67 Coupe with a 3.3 liter 6 cyl. I just got it out of the shop after they replaced plugs, condensor, points, and coil. The car made it from Tuscaloosa, Al. to Gadsden, Al (a 2 1/2 hour drive) with no issues at all. The next morning i try to start it and it is running rough, has no exceleration and will die frequently. Carburetor was just rebuilt so i didnt think that was the problem, looked at the points and they are burnt to a crisp, any suggestions?

IT has been a long time since I replaced points, but sounds like they were not set properly.

I haven't messed with points in a while either but as I recall a weak condensor or bad ground can cause points to fry prematurely too.

If you didn't have this problem before the tuneup and you still have access to it, I'd put the old condensor back in and see if it still happens.

Also, if your distributor is clapped out and wobbly that can wreak havoc on points as well.

First things first though. Check the points gap.

After you have verified everything is in good shape, ditch the points and go with a Pertronix electronic setup and you'll wonder why you didn't do it sooner.

check your voltage at the coil + & - when running it should be 9 volts. 12 volts will burn up your points. it should only see 12 volts while cranking.

yeah i wonder if your power wire is missing the resistor...ditch the points and get a solid state setup...

The points may be of inferior quality or the condensor may be bad ( or the shop didn't really change them). The 12v vs 9v is to prolong the life of the coil but ulitmately, the points pass the current from the coil primary.

+1 on crummy points. Almost all points and condensers are not made either in Mexico or overseas, and for whatever reason just don't give much service. Obviously, your best fix is to replace the pints with a Pertronix Ignitor, which will eliminate anything from burning up or wearing out. In the unlikely event that your distributor is worn out, the Ignitor seems to work well in that environment, also.
Best,

Burning of points, this might be the reason that supply wires are in poor condition, digital techometers, Switch panels. You should use Racing batteries instead of common one.
