Running Rich
« on: 19:46, Wed 14 September 2011 »
Ever sinse my car came back from main dealer it is running far to rich.  I asked the garage to have it back, but they said they are waiting for technical support from head office as they do not know what the issue is.

When up to temperature it idles around 1400 - 1500 RPM.  I beleive it to be overfueling, and because of this, it is running a little jumpy, oh and not to mention the back fire everytime I turn the engine off, after a little gas!!!

Surely this is a simple fix??, but knowing very little about the R5GTT then I  am not really sure - adjustment to the carb???

Any advice would be appreciated.

Regards

Drew

Without an AFR it can be difficult to tell if you are running rich or lean.

You can adjust the idle mix with a smallish screwdriver and there is a slot on the drivers side towards the front of the carb.

With it idling so high it could also be the idling screw set too high.

Or the spring is shot that pulls it back to idle position.

Does sound carb related, sounds like either idle jet is blocked or you have fuel dribbling down the venturi. They prob set the idle that high as it won't run any lower then that.

It will be simple fix once find fault in the carb, more than likely worth taking it off and giving it service and making sure all galeries and jets are clear.

Mine did that when :

Spring was knackered -and-

Mixture screw was too far out. Ran 10.1 on the AFR. Coughed , and then went ..

That sounds like it - every gear change, hesitates and then goes......

Will have to have a look at the weekend then....

Thanks all for the ideas.. :)

I had a very similar problem at start of the year. My carb base gaskets were shagged, so air was getting in somewhere and it wouldnt idle less than 1.5k...

Maybe try a new carb gasket set  :D
