Hello,
Got a 750 a while ago, and just had time to sort some things out, it's been knocking or pingin (don't know the exact english term for it) for a while, but other than that it runs and starts fine.
Checked the igniton timing, it was way off, like at 23-25 degrees with the vacuum connected, but the distributor is already at the limit, I can't turn it more.
Tried to offset the valve timing by 2 degrees, this way I could set the ignition to the correct value and it made the knocking noise go away, but made the car weak at low rpm, and it was hard to start.
So I realigned the valve timing, now I'm 99% sure it's at the correct spot, but the ignition is still off by 10-15 degrees, and the noise is back.
Do anyone have some idea what can cause this?
Thanks!
