Hmm, it had them but I replaced with electric ones. Maybe the hose is still under the dash! That could be related to the idling irregular.
The erratic idle (Slow down and speed up) indicates that a carburetor rebuild is likely in order. The needle and seat probably isn't doing its job.
This is a relatively new carburetor. Maybe it’s related to a vacuum leak. I.E. the replaced vacuum wiper motor ?
Wondering where that hose goes to?
