Hello, my experienced VW mechanic put in my xr700 electronic ignition he said it runs well but said my bad fumes may be a FI cold start valve sticking. Would love to get mechanics input from this forum on that, is it easy or hard to put in, can a non mechanic put that in and how much about does it cost for one?
Thank you |

the initial subject was designated as 74 1.8, so I figured that was for which fuel injection system he needed advice. The main problem calling rich running is the sticking air flow meter flap caused by lean backfire
