I have played around with my sc for sometime. It has always sounded noisy and rough. For that reason I am reluctant to put the car on the road having concerns re. Its reliability. Recently however I decided to get stuck in and try and sort it out.
I always knew that my valve clearances were not correct and have had a number of tries at grinding the shims.I can now say that they are spot on (within tolerance anyway) This was done yesterday, and this morning I gave it a try. Yes you guessed it, as bad as ever if not worse. At first it would not run and sounded as if it was trying to run on one cylinder only. I managed to get it to run by moving the distributor ( electronic) but horrible to listen to and loads of vibration. I believe my valve timing is fine. What have I done or not done correctly. With the air filter removed it is possible to see petrol blowing back through the carb(not misfire). Would this indicate a sticking valve or incorrect ignition timing. Suggestions gratefully received
