Not true, points are just as capable of stopping ignition function as electronic ignition, both electronically, and physically.

Added:

As noted, rubbing block can wear to the point it is too worn to adjust, or, wear off until the metal frame it is mounted to hits the points cam, killing spark

Contact faces can wear from arcing so bad, they can't even be cleaned up to "Limp Home"

Oils can accumulate enough to stop the ground on the points/condenser

Condenser can go bad, grounding the points

So, that is only with two of the components in a points system, there are more, a lot more that can fail any time, rendering the ignition done in, no "Limp Home".

And, that is the truth of it all.

Yep, the points rubbing block will wear down and the point gap close over time if no maintenance is done. Note though, that the two common types of ignition triggers have varied reliability, the VR type two wire sensor is just a coil of wire and can stand much heat in hot oil inside a bike side cover, the Hall type, usually three wire, has electronics in it that do not like high temperatures so much.
I have done a lot of CNC machine maintenance and repair, my system and theory of fault checking initially is look at the mechanical contacts and devices, if there are any, first. The stuff that moves gives trouble over time, like ignition points, whereas the electronic, non moving stuff is highly reliable.

Your site more precisely the gallery infected hand pics WTF did you get hacked?

Nope, as shown, I invented the small-body HEI, and convert process.

In August of last year, while sleeping, a Brown Recluse spider bit my left hand palm. The first 3 pics are of the hand at 12 hrs after bite, then 24 hrs, and then, 48 hrs, just before going into surgery at Renown in Reno. Then, first look after surgery.

Last pic is just after second operation, one week later. Total time in Renown, 21 days.

Spider hitched a ride in a box from Louisiana, got on my clothes, watched me work the rest of the day, got onto my bed when I went to bed, bit me while I was sleeping. I am almost fully recovered, should be done by end of July.

Wow all from a spider its probably a darn good thing it bit your hand and not say the nose or neck heck a spider could get anywhere it wants on your body, I think you were very lucky, Congrats


BTW Since you are obviously a sbc iggy genius , whats your opinion of the Davis DUI? I just bought a DUI have not fired the engine yet , will post a in process pic shortly . Scratch that idea , can't get the pic to post...

A couple of decades ago, Davis contacted me, told me they alone should build "small diameter HEI's", as they were the "best HEI people on earth".

Now, what they build is a modified copy of what I designed, and I have fixed more of them than I care to think of. Until the hand issue, I did one heck of a lot of other brands revisions, changing Chinese electronics to U.S. made good stuff, fixing issues, problems. Same goes for PerTronix (or, Presto-Lite, Per-Lux before Jim Hairston bought them to make PerTronix).

I hope I never get that big that I have to create incorrect information to sell a mundane points eliminator system (PerTronix) as something it isn't, nor over hype a proven HEI system, either.

After I left Team Kawasaki, I worked for Zora Arkus-Duntov in Chevrolet Skunk Works, engine design engineer, specialty areas, and was part of the team assigned to Delco-Remy to develop the coil in cap large diameter HEI. After that, I worked at Holley, Pro-Stock carburetor development, then for Carroll Shelby on the Cobra's, along with various motorcycle development projects and World Championship rce efforts, both factory and private.

The spider bite was strange, in the way the thing got here, and how it got into my bed. Just happy it is getting better, as two options could have happened, if I had waited any longer. One would have been to lose my hand, the other, to lose my life from it. At first, I went to our local disaster of a rural hospital, they had NO clue, I did, they didn't. When they just showed they had no idea, I got our fire department director to hustle me to Renown in Reno, two operations, one week apart, 21 days there, still recovering.

For everybody, please take a close look at everything around you, these things, and lots of other things that can kill are all over the place.

Tuner your an amazing person I dig reading your post always way more than I'd expect , so what did Davis modify on your unit? Davis btw has a pretty good reputation among-est the old school muscle car crowd even some Mopar guys are running Davis. I choose Davis based on reputation and on what I see happening at my local drag strip , all good Davis reports. My Davis is on a stock 305 Chevy marine reverse rotation , vacuum advance delete running 4,000 rpm's on cruise , I want a iggy that not only can handle high RPM's like a drag car but also maintain the R's as needed for a boat and start up each time every time, points is not the answer so I bin'd the stock unit.

BTW not at all in the medicine field but the infection in your hand to me was very very near the point of flooding your blood stream with infectious toxic leading to full blown septicemia, you would have had a very high fever yet felt cold and tired and then passed on, that was a near death adventure with out the adventure .

NOT "amazing", just the same as everybody else. On the spider bite, YES, IF I had waited much longer, I'd have not survived. The end of the cut made to clean the hand up, was 1/2 inch from a major artery in the lower arm at the hand, not good. The worst part is, our local death camp of a, (AHEM), "hospital" had absolutely no clue as to what it was, even after I told them. The surgeon in Reno I got is a great person, his name is "Dr. Dickens", go figure, I got the Dickens treatment.

This part is aimed at everyone, these days, there are all sorts of sinister and deadly insects, animals, even people in our lives every day, so, all of us need to be on extra special lookout for anything that looks like it is hiding, and could cause any sort of health issue.

As far as the Mallory distributor, when personal engine powered boats came about, they used industrial engines, from all sorts of stuff, frm and industrial applications, and most of them had mechanical advance only point ignition distributors. Along the way, Mallory became one of the biggest suppliers of :marine" series distributors to all sorts of car/industrial engine suppliers to the boat industry.

Also along the way, people put car engines in their boats, with vacuum advances, along with mechanical advances, and they gained efficiency, economy, temperatures, making them run a lot better. But, along came the dyno kids, people that flocked to dyno hero's, for dyno tuning. Not so good, dyno's (I have two), are GREAT component development tools, fantastic comparison devices, but, as a final tuning tool, they are just plain miserable.

A dyno actually wants to see two adversities, way rich jetting, and over the moon advanced ignition timing, much past a common sense on road conservative, correct setting. I have seen extremely well built cars go on the dyno for the "Dyno Wars", and win, billions of horsepower, they win the dyno wars, but, not enough power to back the car off the dyno.

Fixing them was dirt simple, set the timing parameters to operate for the street, and redo the jetting in the carb. Fixes them, EVERY time. There is one dyno that is well worth utilizing, it is located inside your pants, at your "6" area, it is called "The Seat of The Pants" dyno.

I get all sorts of stuff to fix, ignition systems, carbs (also worked at Holley for 5 years on Pro-Stock carbs), and Shelby on Cobra cars. Lots of fun, today, I get all the stuff that people can't get fixed, and usually, it isn't that hard, they chose a different path as recommended by others, that wasn't the right path. Around here, anything can show up outside over night, I just fix it, and send it on its way.

I am inside the house right now, had lunch, and watching "Cash Cab", keeps my mind active and alert.
