Ua ntej kho qhov sib tov sib xyaw, nws yuav tsum tau teeb tsa lub maus taus idle ceev mus rau ib ncig ntawm 1000 RPM. Qhov no ua kom lub cav nyob hauv lub xeev ruaj khov, ua rau nws yooj yim dua rau cov txheej txheem hloov kho tom ntej. Tom ntej no, fine-tune qhov sib tov sib piv ntsia hlau kom lub idle ceev fluctuate me ntsis. Thaum lub sijhawm ua haujlwm no, kev ua siab ntev yuav tsum tau kho sab laug thiab sab xis kom txog thaum lub sijhawm tsis ua haujlwm mus txog qhov siab tshaj plaws.
Tom qab ntawd, coj qhov nrawm nrawm rov qab mus rau qhov tsim nyog (feem ntau yog 800-1200 RPM) thiab kho qhov sib tov sib xyaw ua ke dua. Yog tias koj pom tias qhov nrawm nrawm qis thaum tig lub ntsia hlau sab laug lossis sab xis, nws qhia tau tias qhov sib xyaw sib xyaw yog nyob ntawm nws lub xeev zoo.
Nws yog ib qho tseem ceeb uas yuav tsum tau ceev faj thaum lub sij hawm hloov kho, tshwj xeeb tshaj yog nrog cov sib tov sib xyaw cov ntsia hlau, uas yuav tsum tsis txhob txav mus rau qhov tsis txaus ntseeg. Nws raug nquahu kom nco ntsoov thawj txoj haujlwm ua ntej pib qhov kev hloov kho kom koj tuaj yeem rov qab tau yooj yim rau nws lub xeev qub yog tias xav tau.
Raws li ib qho tseem ceeb ntawm lub tsheb maus taus, lub carburetor ua kom lub cav ua haujlwm kom zoo thiab txhim kho tag nrho lub tsheb kev ua tau zoo los ntawm kev sib tov sib xyaw kom haum. Cov concentration ntawm cov sib tov ncaj qha cuam tshuam rau lub cav qhov ua tau zoo, ua kom sib xyaw qhov sib piv hloov ib kauj ruam tseem ceeb.
