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.
