Hi,
We have a 1977 BLMC fully restored Mini.
It has a 1300 cooper motor with twin SU carbs. A while ago the car started to stutter going down the road. This happens after the car is warm and happens during constant speed and during acceleration. A couple of times the car almost dies.
Its a weird fault as it can run perfect for a a couple of miles then it can start to stutter, the only partial fix it to put the clutch in and rev the engine. This is only a temp fix. Also going around different corners alters the fault.
To date we have changed the coil, spark plugs, and the leads and distributor cap. None of this has fixed the problem.
Is this a possible SU Carb issue, fuel issue or something else.
We would really appreciate any advice.
Thanks
Dave
