Metro Turbo Engine Wont Rev


Best Answer Yoda74 , 27 May 2020 - 11:57 AM

It Revs again, it was far to lean on higher revs.

The turbo-specialist at a well known mini-garage took her under his wings. After some adjustments and tries with different needles it revved again but he was not very happy. He overhauled the carburettor, put a new spring in an tried some more with different needles and adjusted the best one untill he was happy.

So now it runs nice and smooth, better than it ever ran since I have it.

Me happy

Hi Guys,

 

My Mini Clubman Estate has a standard MG Metro Turbo engine with ECU.

It revved OK untill it went to a mini specialist a short time ago.

It went to the specialist for brake-revision and for engine adjustments, it did smoke after starting it, its mixture was far too rich.

The mixture also had to be lowered for its MOT, the CO was skyhigh.

 

When I drove it again a month later, it didnt drive well when cold and when accellerating it suddenly stopped pulling at just over 4000 rpm and it wont rev any further.

It feels like a revlimitter.

With this in mind I went back to the specialist and he put the mixture a little richer, it runs better when cold bit still stops at about 4200rpm.

I wonder what causes this.

Any ideas?

 

Cheers
