Hey gang,
'72 1.7 runs fine now, all I had to do was pull the vac line from the MPS. Why the hell would THAT do it? Can I live without it? Doesn't make sense.. Thanks to all who gave input! (IMG:style_emoticons/default/beer.gif) |

It eventually leaks down to zero, it only takes about two minutes.
Hmmm, I'm gonna have to deal w/that, even if there's something else going on. Fuel press is go, spark/timing is go, damn thing idles smoothly and revs freely with the MPS vac line off..what else could be wrong? Am I way too rich or lean? Now that it will at least idle smoothly, what can I do w/MPS disconnected to figure out my mixture? (IMG:style_emoticons/default/wacko.gif) |
