Well I put 20 miles on it and it ran for about an hour, didn't die once. I did have to adjust the air/fuel mixture a little to smooth out the idle, I'm assuming because of the difference in the points. So thanks for the help guys, I'm calling it good for now!!

There is supposed to be a dab of grease on the rotor for lube, if in a dusty environment, the rubbing tab can wear down causing same results.

The new points came with the lube.

Well unfortunately my problem has returned. I drove it 7 miles to the store last night and it wouldn't run right after I came out of the store. At this point I'm thinking fuel. I would have to hold the gas to the floor to get it to fire and then it would die shortly after that. I took the line off between the pump and carburetor, it was clean. Gas pours out of the outlet side of the pump with the line off. I'm going to clean up the pump and check it's pressure. Also I'm going to give the carburetor a good rebuilding. I did check the gas cap, it ran the same without it on.

Gas "pours out"? Does that mean you did a pump test into a bottle while cranking?..or it poured out as it released pressure from undoing it? The second choice means nothing. There is nothing to "clean up" about the pump. Do the flow test. Not a pressure test.

Sounds like it ran for a day or two, then after 7 miles it would not start. When did you try the cap off? You said "ran the same"???
As soon as it would not start after 7 miles was the exact time to check carb squirt down throat. The exact time to pour some gas down throat. The exact time to check spark. Good time to take cap off. You did not say how you got home? You took line of at carb and "it was clean". What was clean? The gas? The fitting?

If you got new points and gapped them and it ran for 27 miles. That's your possible clue. You did something that caused it to run good. Points, condenser, coil, rotor, cap and wiring to all that. Recheck all that. RECHECK THE POINTS. Condensers can be bad right out of the box. Check that choke is not closing. It's also possible that there are more than one thing happening. What else may you have done that day that you forgot you found and fixed?
We are anxious to help. Re read all the posts and reconnoiter.

WE MUST SEPARATE THE ISSUES of fuel or spark. WE MUST figure out which it is. Can't go back and forth. Use the exact time it won't start to find the problem. If it won't start, check to see if the throttle will squirt gas out the holes down in throat of carb. If no gas, pour a little gas down carb right away. If it fires for a few RPM's, you got it solved. FUEL.
If it does squirt fuel out the holes, check spark right away. Something it happening intermittently and that is very hard to catch. Leave air cleaner off on test drive so you can see quickly.
Have you determined that it is not flooding? Sometimes holding pedal to floor, like you said, is a remedy for flooding

as far as pertronix, I have had my truck 35 years,and the only time it didn't make it home was when I "UPGRADED" my ignition to pertronix. I had one fail in my mustang, and one fail in the truck. I could work on points for the rest of my life and still not equal the misery I went through on that windy rainy day switching it all back to points so I could get home. I still have the unit Pertronix sent me as a replacement, But I see no reason to install it. I have a whole case of NOS points I got on ebay.

The Pertronix remark/rebuke is gratuitous at this point. This problem is elsewhere.

However, this thread was taken there: I have had no problem with Pertronix (so far, on 6v or 12v on 235 and 261 high-pressure engines), after I make sure that the distributor does not have an intermittent ground - I ran a ground-wire from a distributor-cap clamp-screw to one of the bolts that holds the coil-clamp to the head.

Nonetheless, since so many people seem to have problems with a Pertronix unit. I keep a spare distributor in my truck, with a set of properly adjusted points. Like many insurance policies, it has never been used. Guess I have just been lucky.

Oh yeah, I almost forgot, I have had more problems with bad new points/condensers than I have had with Pertronix units. Nonetheless, I do not recommend an electronic ignition of any sort on a non-racing 216/235/261, unless you simply want to try something unconventional (that will most likely no measurable increase in performance or reliability). I carry a spare set-up distributor, either way.

It is a fact:
1. Some folks have trouble with pertronix. This is actually Pertronix's fault. They may have a good product but when you sell a DIY kit, this is what you get. Users who don't install correctly. They may also have Chinese reliability problem components. It is, however, a nostalgic "HEI" alternative. I would like to know the return rate on Pertronix and exactly what component fails and why it fails.
But that is their problem. The internet is full of bad stories. They need to fix that negative vibe with analysis.

2. I do not believe, due to dying demand, that there are any U.S.A. made points. The "rules" enacted by our government are a joke. Only some percentage needs to be U.S.A. made or some of it assembled in U.S.A. This could include the box or Puerto Rico made or any U.S. possession. The quality control is gone. Country of Origin is a misnomer. We must endure buying them and tweaking them as far as contact pad alignment and surface of pad. We must find a place that we can buy three, look at them, pick the best and return the other two.

3. The best idea was Langdon. They may be done. Website says they are on vacation. The Stovebolt distributor is "out of stock". A note says "no time to answer your questions, just order and we may call you". I believe I've seen a story about Mr. Langdon withdrawing from activity. Too bad. Can't count on that source anymore. In my opinion.

4. You can not know that NAPA points, which were Echlin, now Standard, are U.S.A. made. Nor Delco, nor anyone else. Possibly old Ebay NOS points that say Delco-Remy are U.S.A. I don't know if a NOS condenser will loose viability or get electrostatic discharge damage in 15 years of storage somewhere, but new condensers are crap* now also. ( * hate to throw in a street term into such a wonderful dissertation, but it fits). Members will survive and keep the 6's running. It will, however, become more of a PITA.

5. Best answer: Install a V8 with GM HEI and go to town with those dual pipes blazin'.

HEI work well on GMC 6's.
