Additional which I didn't mention on the orginal, as follows

when the engine starts the tick-over is @ approx 800 rpm

then rises to 1500-1600rpm as the engine warms up.

The ECU is a MBA 2D system with no TPS, bought from SBD,

Buzz,

so you have no TPS sensor. Can you confirm if the set up used to work fine. Ie you tick over was ok before.

Also can you tell me if the car comes back down to the current tickover quickly or more slowly. does it sort of slowly rev down to it ?

Hi Adrian,

yeah T/O has been fine then all of a sudden raised to 1500/1600rpm and stops there until I start from cold again where it T/O's @850rpm then it steadily rises as the engine gets warm.

Just established what this problem is today, having got the car to run again.  Both throttle spindles in the carbs are bent & the butterflies don't seat properly.  Looks like a carb recon moment! :)
