Hi,

My Sprint is running a Kent fast road cam and 45 Delortos.

Could somebody please confirm what the ignition timing should be set to and at what idle speed/vacuum connected or disconnected.

Also, exhaust cO content too.

Thanks in advance.

Chris.

I run my Sprint engine with the fast road cam and 45DHLA Dellortos as well.
I have set the ignition at 10 degrees BTDC and it runs nicely at that with no pinking.
I do have the vacuum connected as well.

No idea what the CO readings are, it was set up on a rolling road to run sweetly, not necessarily max power.
I typically get about 27/28mpg on classic runs.
