Hi ,I have a old 160 which in the past has always started after two pumps on primer ,its been sitting outside under cover for a week or 2 now i want mow lawn it wont start ,clean the carby ,new fuel ,removed head because it had a porblem blowing head gaskets every now and then but this time it was fine,seems to have a spark what next to try
Squirt some 2 stroke fuel either into the sparkplug hole or into the open end of the carburetor with the throttle open. Use the ordinary cold start procedure and see if it starts then. If it starts but peters out after a few seconds, you have a fuel supply problem. If it keeps going, it may have cleared its throat (if there was a drop of water in a carburetor passage, it may have pulled it through). If it still won't start even with fuel in the cylinder or intake pipe, you have a problem that is not related to the fuel system; loss of compression or spark are the most likely ones.
