Solex dampner question

[718RSK]

Guys,

I confess to not knowing a thing about 911's. I recently picked up a late December '65 car through the help of my buddy Jim B. The car is very complete and unmolested. This is going to be my ladies summer driver after I fix it up for her. She gets to drive, I get to wrench, perfect situation.

The engine appears to be all complete and never apart. Trying to expand my knowledge and reading old posts I noticed that most cars with Solex carbs appear to have the dampner (901 108 650 00) fitted. My car is missing this piece. My question is, was this a standard piece fitted to all Solex equipped cars or something that was phased out before the factory switched to Webers?

TIA,
Joris

From those in the know, it was installed as a rudimentary emissions device, to slow throttle action on decal. The theory was that if the throttle closes a little more slowly, you puke less unburned gas into the air. What sucks is that when they don't work, you end up with crappy throttle return performance. I took mine off. I have two NOS ones in bags.

Thanks Kenikh,

Am I right in assuming that they were likely used on all Solex fitted cars but that owners/mechanics would take them off when they got sticky etc. ?

My generation used to call them 'dashpots'....

Here's what wikipedia says:

Dashpots are commonly used in dampers and shock absorbers. The hydraulic cylinder in an automobile shock absorber is a dashpot. They are also used on carburetors, where the return of the throttle lever is cushioned right before the throttle fully closes and then is allowed to fully close slowly to reduce emissions of sudden deceleration (compared to deceleration without a dashpot)

Spot on. They do nothing other than add Concours points.

For the guy behind you. . . so you don't shoot fire onto his bumper at the end of the straight, right?

The guy behind me is never close enough for it to matter.
