[QUOTE="gavan, post: 1389776, member: 2598"] when you turn it and you noticed your engine is slowly starting to stall, then its leaning out of the fuel, then if the RPM increases then you are making it rich :) tips to tune? off your engine turn your AFR screw to the tightest you could, then unscrew it bout 3 rounds. then start your engine and adjust the idling screw(the biggest one there for proton) make sure the idling is stable(around 900rpm? dun forget to rev the engine abit each time you do an adjustment) then you slowly adjust your ARF screw lo lean it...noticing the engine sound each time you turn the screw wether the engine pings(knock) turn it till you notice a drop in RPM(like the engine is choking) then turn the screw half way out(richen it) then it should be okie laa after that, adjust the idling again then you should be fine. do tune it after driving a while to suit your needs =) if you feel the RPM is hard to climb (eg:it only climbs at early RPM then the engine feels like it doesnt wanna rev) then you should richen the fuel mixture a lil more =) hope this helps.... just my two cents....if any sifoo out there got better tuning method please help our fren here too ya +) [/QUOTE]
