I recently had problems with my 73 911s when it was warmed-up.
It ran fine above 3500rpm, but poorly at lower rpms. After some reading about MFI, I removed the thermostat and found that the thermostat rod only moved 2.5mm. I read that it should move 4.75, so I removed a few washers/disks. It now runs fine.
My question is, do I now need to adjust anything else to compensate? It does smoke a bit which it did not do before.
Thanks for your help.
