Gary_Ash Posted October 3, 2020 Share Posted October 3, 2020 I remember that I was told as a youth that, in an emergency, you could set the distributor points gap using a matchbook cover as a thickness gauge. It occurred to me today that I don't know where I would find a matchbook now, as the number of smokers has decreased, restaurants and bars don't hand out matches anymore, and smokers now carry little butane lighters. Besides, modern cars don't have points. My wife has a container of matches for lighting the fireplace and tossed a few old matchbooks in there that came from her father's collection he acquired on a cross-country trip about 1955. I checked one with the micrometer and it came out 0.013", somewhat less than the 0.020" recommended for a couple of my old cars, but would probably work well enough to let the engine run until I got home. I don't think I'll put a matchbook in the glovebox, though. Some of those old matchbooks wound up with my brother-in-law, who has been selling them on Ebay for $5-$25 each, especially the ones from long-gone Las Vegas casinos and the ones where the individual matches were shaped like beer bottle or something. I checked a couple of my credit cards and driver's license and they were all 0.030"-0.032", OK for gapping plugs but maybe too thick for the distributor. I wonder what the modern day equivalent of the matchbook cover would be? 5 Link to comment Share on other sites More sharing options...

Rusty_OToole Posted October 4, 2020 Share Posted October 4, 2020 Don't be so cheap, buy a set of feeler gauges. They will last for years if you don't use them to set the valves with the engine running. 3 Link to comment Share on other sites More sharing options...
Fossil Posted October 4, 2020 Share Posted October 4, 2020 Business card is or was .010". Folded in half would give you your .020" gap. This is what I always went by. Link to comment Share on other sites More sharing options...
Frank DuVal Posted October 4, 2020 Share Posted October 4, 2020 Worn dime was for setting the points! This was in the day of the silver standing Liberty dimes, so they wore thin in everyone's pockets. I can just set points by eye. Not correct, but enough to get the engine to run.😉 5 1 Link to comment Share on other sites More sharing options...
Jeff Perkins / Mn Posted October 4, 2020 Share Posted October 4, 2020 Many years ago when I was in my infancy of Model A ownership (early 80’s) a club member set my points with a matchbook. I then kept some of these, pictured below, in the car. These were my fathers, from 1958. As I state in my profile, he was a car salesman at this dealership. Unfortunately he passed away in a single car accident in October 1958, coming home from work in a Volkswagen Beetle. 1 1 Link to comment Share on other sites More sharing options...

Worked great. The cellophane trick is for quick and dirty timing adjustment. Set the timing mark on the pointer. Loosen the distributor or points plate and turn it opposite rotation. Slip the cellophane between the points and turn the plate or distributor against rotation. At the point that the cellophane will pull out with a very slight drag. tighten everything down and you're good Link to comment Share on other sites More sharing options...

edinmass Posted October 4, 2020 Share Posted October 4, 2020 (edited) Here is a photo taken in the Cotswolds of England, just after crossing over into Whales, on a dirt road with no cell service, and no signs of civilization for miles. Why does this apply to a match book conversation? Less than a minute after this photo was taken, from the back seat of a Pebble Beach Best of Show winning car.......the points broke into pieces and the car dumped down to four cylinders. I had spare points and some tools, so I was able to make a roadside repair And get the car running up on eight again. No matchbook to set the points.......so we used the Boss’s business card. Worked great, and we got to lunch on time.........the car? Come to Pebble Beach nest year for the reunion of all the Best of Show Winners..........if you buy me a drink, I’ll give you a ride. 👍 Edited October 4, 2020 by edinmass (see edit history) 2 Link to comment Share on other sites More sharing options...

Ed Luddy Posted October 4, 2020 Share Posted October 4, 2020 Got me thinking that I need to buy a set of feeler gauges. Then I can't remember how to set points anymore! Last time I had to do it was around 2002 on my 63 Acadian. My Karmann Ghia still has points, but just had a new distributor put in and set up at the Bug Stop, my Chevelle has been changed to HEI, sold my 67 Pontiac so maybe I'll be okay without a set for the near future.

TerryB Posted October 4, 2020 Share Posted October 4, 2020 Remnants from the golden age of point ignitions. The feeler gage blades are .016 and .020. The tool with the points stone is .023. My early motorcycles had points too so the tools were a necessity. Link to comment Share on other sites More sharing options...

edinmass Posted October 9, 2020 Share Posted October 9, 2020 It’s hydraulic pressure in the braking system, you can see the pressure increase as you press harder. I use it to check for brakes dragging........had it happen once. Could tell we had a problem, as the guage red 25 and the pedal was free.........didn’t take long for them to overheat and lock up.

J brakes can be a challenge. Here you can see the pressure on the guage at a stop light with light pedal pressure before actually coming to a stop. Speed is just under 20 mph, engine is at idle....525 rpm’s. It’s reading about 100 psi. It’s easy to max out the guage in a panic stop.......so they tell me.🤔 It was 11pm, so the dash lights were on. A few seconds later we were doing 70mph with the top down and 48 degrees.......a chilly ride.....but lots of fun. It was the ACD meet in Auburn in 2019.

keithb7 Posted November 21, 2020 Share Posted November 21, 2020 I read two different articles recently about dwell time. One stated that for every degree dwell was out of spec, so was your timing. 1:1 ratio. If your shop manual calls for 46 degree dwell, if it's set at 40 degree, your ignition timing is out 6 degrees....Then in another article it claims that adjustments in dwell time effect ignition time 1:2 ratio. As 50% accounts for the points ramp up the distributor cam, the other 50% is back down the other side of the cam lobe. Either way, the effect on your spark timing is considerable. A feeler gauge is a simple method to start setting the points. When you adjust the points you are affecting the dwell. The matchbook cover will get the engine running and get you home. When you get home and have a dwell meter, then it's time to take it out. Set the dwell properly within spec. Then a vacuum gauge helps to set the A/F idle mixture screw. Next reset your idle RPM....Then get the timing light out and check/set the timing referencing the front pulley timing marks. Just my .02 cents. 1 Link to comment Share on other sites More sharing options...

padgett Posted November 21, 2020 Share Posted November 21, 2020 Agree, great place to visit particularly if you speak Mid-Atlantic Bland. Got asked once in a Fish & Chips (entirely different from what is in the states: choice of 27 different kinds of fish) if was a BBC announcer. Companion thought it was hilarious. Meanwhile a credit card can also be used to set points and can use a nail file to remove deposits, is just a way to "get home" and set properly.
