lean out the carb a bit till it stays running,hi, i did nothing on the carb since i unpack the motor out of box!its walbro 668 and fire up first time today.
yep, just like the nitro 2 strokes, starts to rev higher since it's getting leaner at the end
Yes, that's normal. How many times have you ran it, and for how long each time?
!
BE A LITTLE CAREFUL !!!
YES, as they say, it's normal, as when the fuel's leaning out (running out) the revs will rise ... BUT .... and it should only be for a short while but if the revs rise higher than the take-up of the clutch, IT WILL MOVE FORWARDS ..
Take a little care where you store it if idling. It's better to use a little throttle anyway and not simply leave at idle ..... many theories on that one.
Al.
just break in the first tank and i shut it down for safe when the above situation occur.if thats normal,how many tanks should i run for break-in stage before tuning the motor in good performace?
