WHEN I HAD THE SUPER 77 CARB REBUILT I ASKED THE SHOP TO INSTALL A $9 SHUT OFF VALVE FOR THE CARB.I THOUGHT THIS WOULD TAKE CARE OF ALL THE ROTTEN FUEL HANGING IN THE CARB UNTIL THE NEXT TIME YOU FIRE IT UP-IT WORKS!!
JUST TURN THE VALVE TO TO CROSS POSITION AND LET HER STARVE OUT FOR FUEL.I DO THE SAME FOR MY GENERATOR-WORKS THE BEST.
IF I CAN EVER FIGURE OUT HOW TO POST THE PICS OF MY 77-I'D REALLY LIKE TO SHOW YOU.
SO FAR NO LUCK BECAUSE APPARENTLY THIS SITE NEEDS REALLY LOW PIXELS TO POST.
ALL HELP IN THIS MATTER IS APPRECIATED.

???What about lubrication as the saw runs down? Or is there enough lube remaining in the crankcase and cylinder? I have always been afraid to run a two cycle out of fuel-oil mix.
Perhaps I am being too nerdy...

I know this is an old post, but, I've seen many concerns about lubrication of running a chain saw dry.
As it is idling, normal lube is occuring, when it starts to sputter, I put it to full choke.
It will die pretty quickly, plus empties more fuel from carb.
FWIW,
thanks,

It will die pretty quickly, plus empties more fuel from carb. FWIW, thanks, If the saw is running, the fuel pump is pumping so choking it to death will not drain the carburetor. The fuel line is as much a problem, if not more, as the carburetor diaphragms. I've opened up many carburetors that have been sitting idle for years and they have been surprisingly clean. Sometimes I find oil, like the gas evaporated and left the oil, but not much else. Think about it, unless there was water in the fuel, there is really nothing in the carburetor to go bad. I've never found a diaphragm that has deteriorated and turned to goo like I have seen of fuel lines, thou the diaphragms will stiffen up some. IMHO running the saw til it dries up won't hurt anything because the starving time is quite short, usually no more than 5 seconds, and there is always some residual oil left from the last cycle. |

Ill agree with that.
I let all of my 2 stroke toys run dry at an idle, then I put the choke on and let them die out again. Theirs plenty of residual oil for all the internals as long as your near or at idle.

How will it starve for oil if you are running a premix? The lubrication comes from the oil mixed in the fuel
