(turn anti-clockwise)3.then start your engine and adjust the idling screw (the biggest one on the rightside of the carb for proton) *** make sure the idling is stable around 900rpm n dun forget to rev the engine a bit each time you do an adjustment ***4.then you slowly adjust your ARF screw to lean (turn anti-clockwise)...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)/ (turn Clockwise) until u notice the idling of the engine is smooth/stable5.adjust the idling again to maintain at 900rpm, then you should be fine. (do tune it after driving a while to suit your needs =)Note: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 =)(turn clockwise)Well guys i'm also trying it out....no tools /O2 sensor...just by listening and feeling your car's body. may need to do additional adjustments later / after driving awhile.Will keep u all inform/postedD</blockquote>
