help identify IDLE SPEED & IDLE MIXTURE SCREWS (PICS INSIDE)

**speedibot** · April 22nd, 2011 05:21 PM

Gud day mga gurus! just want to ask some help saan at anu yun IDLE MIXTURE AT IDLE SPEED SCREW sa isang 2e carb. I've been googling pero kinda confused pa din ako dahil hirap ko ma identify which one. Ayoko din paglaruan yun mga screws kasi I might get it "screwed" pa.....lagot tuloy.My mechanic had done some repairs kasi at sa hesitation nyang i-warm up kagad yun engine, tinodo nya yun idle speed at fuel mixture para raw makatipid sa oras.Unfortunately after that, medyo pansin ko lang lumakas ako sa konsumo at maamoy ang exhaust ko.Of course sigurado hindi nya nabalik sa tamang timpla kaya I'd like to D-I-Y nalang...I've attached pictures, gusto ko lang malaman po ano yun #1 at #2. Correct me nalang po pero sa initial understanding ko...yun #1 ang IDLE SPEED SCREW (RPM) at yun #2 na nasa baba ng carb ay ang AIR/FUEL MIXTURE SCREW....thanks and more power to the forum!

i have trouble seeing the picture pero try having someone pressing the gas pedal and look which part moves, usually dun nakakabit yung idle speed screw sa moving part, the idle up screw naman is connected to a device na may vacuum hose, and the mixture screw is usually inserted sa non-moving part ng carb.

Thanks sir genobreaker47 for the response. You are right. The #1 may be the idle up screw kasi katabi nya yun throttle and the screw has a 45 degree angle and i've read in another forum na yun yung idle speed screw raw. The second one is just under the carb and positioned in a non-moving part (near sya sa I think a hose sort of...)kaya baka yun yung mixture screw. anyways salamat po sa reply. I'd still appreciate more suggestions if ever, tomorrow morning ko nalang paglalaruan yun mga screws kasi gabi na...its hard to see ng naka flashlight...thank you!

tagal na po pala nito, na identify na po ba un screw no. 1. un pong 2 ay air mixture po yata, pero di ko sure ung 1, kung yan nga po ung idle speed, pano kya ito i adjust, may nabasa ko paluwag less RPM saves gas, tama po ba?? hope may mpadaan po dito at mkasagot. tnx tnx
