948cc with poor acceleration...

It all comes out of the one refinery........... If you think you have carbon in the chambers (running on..) - then run some water through the system - hot engine revving above idle - put the dizzy vacuum lead in to a jar of water and let the carb suck it in.....

I have tried this before on my old Hillman Minx and it does not work, i put a ton of water through it, but it still ran on and when i pulled the head off it was absolutely caked. There is no subsistute for pulling the head off every one in a while and giving it a clean. For the price of a headgasket and a couple of hours its not worth skipping.

There is a limit to what it can tackle! Years of hard build up can't hope to be shifted by a cup of water.... The best way to clear it is to drive the car really hard and long............

hard and long been doing that to mine for years

Go hard or go home

You have a 948 that can go uphill in top gear without slowing down? What strange sorcery is this?!

[bmcecosse]

Rather depends on the hill I imagine!

Perhaps a molehill or a speedbump... My Mog (which has a stock 948) doesn't make it up the really steep ones without losing twenty miles an hour! Then again, it could probably use a rebuild.
