I have a 1978 Porsche 924 and I am having some issues with getting it running right it is running realy rich for one, don't know if that is the way it is sapoto run I am having issues with the timing and it is not starting right it is turning over hard and sometimes not at all. I bought the car it was not running I replaced the cam and alternator and had a garage time it for me it seems to run okay but I continuously have to adjust the air to fuel mixture to keep it idling right. I don't know what is wrong I have the hanys manual for it but it doesnt help that much I think that the timing is the isusse or the throttle body I need some help pleas
