Problem with my KR

[salvatron]

hi there.. need some advice on my KR.. i'm having a hard time starting my bike when it is cold. the only solution is to push start. the thing is my batt is new only 2 mths old and i had just serviced my carburator and change a float valve because petrol is leaking frm my carb. and i also changed fuel c.o.c.k coze it was leaking as well .. and my spark plug is new too.. when changing the fuel c.o.c.k , i saw the mech draining out some petrol and pouring it into a bottle that was ment for EO , after he fixed the fuel c.o.c.k .. he poured back the petrol into my tank .. has it contaminated my fuel?

if the engine oil bottle was empty, no. if it has engine oil within, yes.
