IaM-Ray posted:I would probably have the dizzies fixed first and then try to see if the carbs can be tuned after all have you driven that car for a year yet? I don't think so. It is just that maybe a few forums or another opinion might develop with refurb/new dizzies.
There may be other expert P mechanics that could comment.
Anyway, I like to take it step by step before going on a parts change frenzy.
There are many forums: Pelican, Rennlist, PCA, 911 REGISTRY.....all have blurbs going back 15 years with the exact same Weber/flat spot issues! All(95% plus) remedied by PMOs after switching from tired/inadequate Webers with comments by top guys at RENN/Patrick Motorsports/etc.....you can read them all. Virtually IDENTICAL problems remedied with upgrades in PMO and recurved DIZZIES.....the literature all backed up by the GURUS of Porsche performance. I did not take this lightly without turning every stone and every angle by the most qualified guys in our hemisphere.
