Hi, not been on here for a ages and have a problem thats been bugging me for a while!!

I have a Williams 2 with a problem! On tickover it sits at 1500 rpm for the majority of the time and redlines at between 3600 & 4000 rpm? Do any of you have any ideas what this could be?

Another problem which could be related/unrelated is that when it gets warm it seems to lose a lot of power on acceleration and sounds like its suffocating itself. Possibly down to a K&N that the previous owner had fitted? Might try going back to a standard air box.

I really hope someone can shed a bit of light on this please as im rapidly falling out of love with this car after so much time and effort restoring it.

Thanks

Tim
