i got an nrg power lc and had the engine rebuilt with 70cc stage6 kit, 70cc crank, new bearings and it wouldnt stop leaking oil so i removed the oil tank and hoses and been pre mixing using the oil i used to put in the tank i just want to know if this is the correct type of oil for pre mixing and how long the oil takes to settle on the bottom of tank and the throttle cable on the oil pump is it allright to leave it off

thanks for replies

yes as you are premixing it then 2 stroke premix oil is what you should use,it will settle to a certain extent overnight on the tank base but a quick shake in th morning will mix it back up easily,aslo leaving the cableon the pumpis ok but if i were you and it was air colled i would take the pump out and also the oil pump drive belt off the crank shaft if its water cooled leave it on as it also drives the waterpump,
