Reply to "EFI versus Carby"

FWJMember

The main issue with spark fouling is due to high cams producing not enough vacuum at idle speed. To overcome if everything else is fine (carburetor settings) is to rise idle rpm to anything between 1250 and 1550 rpm.
I know it’s ridiculously high but the only solution. I am hoping with dynamic timing setting in combination with an EFI the issue could be partially cured which allows a bit lower idle rpm as for the carby
