Hi I have a charade sg and am having problems with distributor adjustment. The engine is an HCC. Correct me if I am wrong; the procedure i am using is connecting no. 1 lead to a strobe gun. While the engine is running (idle speed), I adjust the distributor by making the crank shaft pully markings aligned. I am not sure if i need to diconnect a pipe from the carburator! After some kms the engine starts to misbehave again and I have to repeat the above procedure. Am I doing the right thing? Can anybody tell me from where I can get a workshop manual.
