I recently swapped the 999cc engine in my 1990 Uno for the 1108 FIRE, however it refuses to run properly. Mainly it will not pick up properly from low revs takes ages to rev up from full throttle at tickover, and needs about half throttle or less until about 3000rpm-ish. Once above this speed it runs reasonably but still seems a bit 'flat' in acceleration. I have tried altering the ignition timing, which improved it a bit but the timing is now the most advanced it can be i.e. at the end of adjustment. I'm not entirely sure if the vacuum advance unit is faulty, it doesn't draw air, so the diaphragm is ok, but doesnt have much movement on it... is this likely to be the culprit??
Have also tried adjusting the mixture on the carb which doesnt make much difference to it......
Any help much appreciated, as I have to drive to London fromm Devon on Friday, and the MOT is coming soon...
