Mixture question



I say that the mixture at idle can be misleading sometimes. But that's
where we check the A/F ratio for cis- so who knows.

I've heard that this stinkin E10 gasoline burns at 13.9:1 now instead
of 14.5:1 - so that could throw it off too.

I say - Seafoam it - make a nifty smokescreen - and then check it again!!!
