Blast from the past - who knows what this is?

+ 1 on carb adjusting tool.
The points dwell adjusting tool has a bend. I'll post a pic if I remember where mine is.

Before emissions controls blanketed the early ‘controlled’ vehicles, one could just slide open a door on the GM distributor, insert the correct hex key and set the dwell. GM switched over completely to HEI in 1975 as I recall. Prior to this, as the motors were increasingly covered up with thermal vacuum switches, vacuum lines, EGR valve, etc. it became increasingly difficult to reach the distributor.

I recall Ford having a vacuum controlled ‘decelleration control valve’ that kept the throttle from closing too fast due to emissions reasons. Sadly, it often malfunctioned.

I’m curious to see what the tool is for.

Car manufacturers had to detune engines so radically to meet emission standards the engines would stall if the throttle snapped closed like normal. They introduced the DCV to bring the throttle plate in the carb to the closed position in a controlled manner to prevent the engine stalling when vehicle is coming to a stop.


They also introduced the electronic idle control solenoid. The engines were so gutless they had to increase engine idle speed to keep them running on A/T vehicles in Drive but if you shut off an engine that was running at the higher rpms when trans in Park the engine would diesel. The EICS would be set for required idle rpm in gear and the carb base idle screw was set much lower. then when ignition key was shut off the EICS would de-energize allowing throttle to close further to the base idle setting allowing engine to shut down w/o dieseling.
 
Last one till I open some more boxes. Fairly easy. What are they?

Not positive, best guess is gauge for timing chain guide wear.

Need to adjust carburetors and distributors?
I gotcha covered.
Somewhere around here there's one or two with a flex end. And a bunch more distributor wrenches.

No one guessed it.


Carb float gauges for Rochester 2SE & E2SE carbs.



That's all for now until I open some more boxes.


Others can post up their own pics of unusual/defunct tools from the past. Go for it!
 
D*mmit!
I just use a drill bit or the paper gauge that comes in the rebuild kit.
I have some good ones to post. Still use lots of them.
 
Yessir.
This particular application was for the parking brake on a F700. Hydraulically released spring brakes. They somehow managed to break the control valve.
 
I probably own more home made tools than manufactured specialty ones, or at least equal. Because cheap. [emoji16]

My money went into my MIG set up. Mig set up make me more tools. [emoji1303]
