My 18 year old leaf blower, an ancient Sears model, ran great until recently. It starts fine, it runs at full power just great, but when I turn down the throttle, it stalls. It then is almost impossible to start again unless I wait ten minutes and try again. It runs great at full throttle but every time I reduce the throttle, it stops and will not restart. Previously, when I throttled it back, it would just slow down and idle. I always add stabilizer when I buy a one-gallon refill of gas.
I checked the spark plug, looks fine. I replaced the fuel with new gasoline plus new oil, no luck. The manual says the carburetor cannot be adjusted.
Any idea what I should be looking for? Would like to keep the blower for another twenty years. :-)
Thanks for any help
