CIS testing results question

[Damon88]

1983 US new rebuilt engine. I Have a 50 break in miles. Starts fine both cold and hot. But smells rich.. but who am I to say for sure...hah

fuel distributor #0 438 100 077
WUR 090 ( brand new unit from K jet)
Cold pressure temp 11.4c
1.3 Bar pressure test valve open
4.8 Bar pressure test valve closed

Hot Temp
3.5 minutes 3.1 bar
rest pressure
10 min 1.3 bar
20 min 1.1 bar
30 min 0.6 bar

Did this test twice to make sure, it was my first time doing this procedure. Thanks to a great video done by Klassik auto on YouTube. From what I'm reading, the Bentley manual it shows its "Rich" on start up ? I don't have any way to test air/fuel without taking the car to the local porsche dealership. go easy on me... first timer lol Cheers.

Pressures won’t tell you mixture. I was in a similar predicament, and just installed an AFM gauge. Probably cost less than a trip to the dealer.

Whereabouts are you on the Island? I'm just outside Victoria and have a CO meter which you could use if you're local. Send me a pm if you're interested

Thank you for the reply. Did you have to install a second 02 Bung for this set up?

Which AFM gauge did you get?

Thanks.
