This is actually from the Haynes Manual: "It must be noted that to get the very best setting the final adjustment should be made on the road. The distributor can be moved about ¼ of a division (i.e 1*) at a time until the best setting is obtained. To obtain the best setting under running conditions first start the engine and allow to warm up to normal temperature and then accelerate in top gear from 30mph to 50 mph, listening for heavy pinking. If this occurs, the ignition needs to be retarded slightly until the faintest trace of pinking can be heard under these operating conditions. Since the ignition advance adjustment enables the firing point to be related correctly in relation to the grade of fuel used, the fullest advantage of any change in fuel will only be attained by re-adjustment of the ignition settings" "Method 2) Advance the timing to obtain the highest RPM at idle. Then, retard the timing just enough to reduce the idle by 100 RPM." |

I don’t know the third one in the first row or the fourth one in the second row, but I have an idea about that one.

"These bags (1900-1960s) were used on road trips especially in the desert. The bag was soaked first, then filled and hung on the car’s hood ornament or from the bumper. As water seeped slowly to the surface, it evaporated and cooled keeping the water about 12 degrees cooler than the air. As both air conditioning and coolers for cold drinks were both unavailable to drivers, these offered a somewhat refreshing drink on a long drive." Additionally, if hung in front of the radiator, cooler air was passing through it and if overheating still occurred there was the water in it to replenish the boil over. |

Newer versions look like the below, or one can use a wideband O2 sensor setup or other similar device(s) now but old school people used old school tuning devices... like their ears, basic vacuum gauge, etc.. The Weber carburators were finicky but when they were tuned well, the car just idled beautifully, especially the old F1 cars, and some exotics like the Weber's on top of the Ford Cammer engine below. |

*On a funny note: That girlfriend ended up sticking with me, funny fuel lever and all. We married in '72 and just celebrated our 52nd anniversary. To this day, she whines when the gas gauge goes below a 1/4 tank, fearing that we'll run out. Last edited by sygazelle; 01-15-2025 at 06:19 PM.. |

Below is a pic of a 66 Pontiac GTO Tri-Power setup. Not Weber, but made by Holley. The linkage was quite complex and tuning was an absolute royal PITA and required significant finesse to do correctly. It was always a great idea to have additional fuel filtration as the jets in the carbs plugged fairly easily causing unbelievable frustration to a tuner. The car was quite fast for its day and had bias ply tires that were laughably poor at maintaining traction - so much so that it would just smoke the tires to the rims if you hit the gas really hard from a stoplight. Very very impressive car and an amazing piece of auto history. Adding even 20-30 hp to a car like this with a large displacement motor (389 cu inches) required significant bolt ons and money. Now, we are spoiled with our BMW's insofar as just buying a RaceChip, or JB4, etc... and adding 30-50hp or whatever without having to tear into the motor, or even get our hands dirty. Even a lower tier non M modern BMW is faster than the 1966 Pontiac GTO Tri power which was beastly for its day. Progress! |

That is an amazing old school piece of tuning. I never used one but some of the old timers I knew had used them before other tech for tuning somewhat supplanted it. It was the same with ignition systems. The old points, and non-HEI type distributor systems were often replaced with newer tech on the older motors. I remember taking my distributors to the speed shop so they could grind down the weights and put different centrifugal springs to adjust the timing curves to better match the mods on my cars. Otherwise it was just hit or miss. Worth the $3.... Some of the crazy stuff we did to make our cars faster in hindsight were kinda laughable now - but they were legit and plenty of guys spent countless hours making tuning adjustments that in total probably often were worth less than a couple HP here and there. Now? Dyno tuning and adjusting fuel/timing curves using a laptop. I still have a bunch of metering rods and hangars for Rochester Quadrajet carbs somewhere in my basement. I'll probably never need them but it took me forever scouring junkyards to find them. Old times, good times. |

dad pulling the reserve lever a few times. Also, when dad judged we were getting low on gas, but not yet on reserve, he’d switch to reserve just before passing a car on a 2-lane highway, then off the reserve after the pass. He didn’t want the engine to quit halfway through the pass. And now folks are probably wondering how a heavily loaded 36 HP VW micro bus could pass anything. Well, dad was a master at energy management and drafting.

after having the engine rebuilt. I had to buy the intake manifold from a parts house in Canada. Also, I had my overhauler install the Cortina GT camshaft. Between the 2-bbl Weber, new cam and tubing headers, that little pushrod engine really perked up. As the the Weber, I got pretty familiar with fine tuning it with the jets and emulsion tubes. This required some experimenting, but it was very driveable.
