please identify this part, I've never seen it before

bolted onto the carb  but not conected? Thanks CB

Dashpot.  They turned up in 1970 to close the throttle blades fully when the car was shut off to prevent dieseling.  Were they sooner than 70 on four speed cars?

Thanks, something to remove I assume?  Or did the previous owner install this because it was dieseling? Sits on my 69 RR.

I could be off on the year, is it a four speed car?  It doesn't harm anything as far as performance or function.

It's an aftermarket idle solenoid, used to prevent dieseling on shutdown or to kick up the idle speed for A/C.

Was I correct on the 1970 factory application John?

[Nacho-RT74]

as far I know they were part of equipment since 73 or 74. My car got it, BUT was being used to increase iddle when AC is conected. However electric diagrams show it like iddle solenoid and sourced from Ign circuit

[John_Kunkel]

These were used from the factory on some applications starting in '70 but the one in the OP is obviously aftermarket.
