Methyl alcohol burns slow and cool and I'd expect ethyl to do the same.
In straight methanol applications the richness needs to be increased a
LOT. Some racing type 1 engines using methanol don't even have cooling
fans (midgets).
It's been years, but it also seems like the need to light it off at
45-50 � before TDC, maybe earlier. An air cooled L-Jetronic engine at 8k
feet is going to be somewhat rich anyway. It seems like a dose of
alcohol might be just the ticket.
