the cap protecting the fuel needle is below the air/fuel ratio screw... notice the big bolt??... the needle is inside...

the gold color nut left side is jz to secure the fuel line entering ur carb lah... has no effect... but if u loosen it, ur fuel line will bocor and squirt out loh...

how to adjust must ask sifoo fstrader adi.... me still noob in tuning...

Hello to every Forummer, I m currently facing problem with my Carb and i do need fellow forummers' advice. Im using 4g91 engine carburator, and the engine hessitate and nearly die off sometimes while off idle..For example, launching at traffic light after it turns into green..it is very irritating, and im now thinking the solutions for this problem. It is due to tunning of the carb? coz it only appears sometimes not everytimes...sifu pls help.
