hi m8 yes ur car is running rich, would also explain foor fuel consumption (if its not ur tank)

yes i found when i set timing according to book it ran horribly,

dave if its backfiring its because theres too much unburnt fuel, warm car up first,  retard timing slightly just by ear so engine isnt bumping around and sounds sweet, and reduce the throttle adjustment screw so it doesnt tick over so fast.

i hope someone else can also offer some advice,

regards
Chris

Can you believe this was done on purpose to show off at the Tuning show.
Maybe I am just getting old. :lol:

My car just diesels instead - just as embarrassing.... I saw Dave Arnot's great little barchetta and that really goes for it - big flames.

(BTW - anyone spotted the Barchetta on ebay - badly described as a Fiat 600 Abarth. Someone might get a bargain as they cost around €8,000+)
