I used a spare metal ring that goes on the shutoff valve from another IP as a spacer. Car shuts off instantly now.

pictures, please.

Are you suggesting that slop in the linkage should be considered a common culprit?

is it due to an aging diaphragm, or worn linkage elements?

I have noticed this slow shutdown symptom on other cars, mine certainly isn't perfect. But if its a simple fix like that... I'll keep that on my JY 'To Do' list.

clever.

thanks

Neither, I tested it against another one I had and both acted the same. I believe the problem is that my adjustment of fuel quantity was still allowing fuel flow, the linkage had at least another 1/8" or so of play.

I meant the linkage of the shutoff valve itself, inside the IP. Doesn't that arm lead somewhere on the 'control rod'?
