[DeTomaso] Passing emissions - or anyone got a carb for me?

[Dave Londry]

That would be enough to get me through for sure Thomas,
 but my 'regular' fuel is 94 octane chevron which is 10% ethanol here.
I've been thinking of adding 5% methanol to that,
 but I'm running so lean already that it's a bit scary.
