T25 is doing my nut in

It won't go off until the water is upto temp ish, should back off a little at full throttle

 

I will try that in the morrow....

 

Be sure to post a video for comparison

 

The second butterfly in the pierburg is only opened under load through engine vacuum so it won't open when engine is off (or even with the engine idling or being revved).
Choke looks like its set correctly with 3mm gap. Mine does the same when the engine is off.

 

Oh yeah I forgot about all the vacuum controlled gubbins on them

 

Its a PITA when it goes wrong. Atleast its not the later model with all the electric gubbins too.
Fast idle valve on mine is playing up at mo. Tries to idle at 900 revs cold which it doesn't like.

 

Yeah mine was idling on so thing way too high before. Would be pleased to see it just run tbh

 

I did the throttle thing and my butterfly hardly moves ,just to check it will back off all the way there is a lever near the carbe body you can move and it should open fully [can post picture]...
