I have tried cleaning and reassembling my Dash pot but the thing just keeps sticking even after i hit it with a shot of silicon spray. so i want to replace it.
Any suggestions of where i might find this obscure part?
I know the stealership will have it. anywhere else?
just so we can all celebrate knowledge a dash pot is there to slow the closing of the throttle to prevent backfiring. yay!
Cheers
