If you insist in driving something this weird (and neat!), I see no
course of action other than getting it dyno'd by someone who
understands 4-cylinder performance cars. Ask around your area (where
are you, anyway?) for a serious racing tune-up specialist. whe (s)he
gets it on a dyno and engine analyzer, (s)he will be able to figure
out the best settings for ignition and carbueraton.
