Have LawnBoy model 10324 with a 3 year old new motor (short block). Has been running perfectly.
Today went to mow yard. Started a bit harder than normal but attributed that to the 45 degree weather.
Mower ran perfectly for about 45-50 minutes when suddenly it "went wild" seemingly running at as high RPM as possible and smoking like crazy....which it never does. Machine is immune to the throttle control.
Initially figured the air governor spring had become un-hooked but the spring was attached properly. Governor assembly moves easily to the touch, is not bound at any place during its travel and appears un-broken. Cleaned all the linkage and everything moves when the throttle control is moved, choke appears to open and close and the spring for the governor shaft changes tension like it should.
Upon restarting, the machine ran wide open, started to die on its own and then produced a little pop apparently a backfire and stopped.
Now machine will not start. I'll check the crankshaft seal tomorrow to make sure it is in place, but the loss of RPM control has me baffled.
Any suggestions?
Thanks
