This is a new one to me. I've never had this exact issue before and have this thing completely tore down and still haven't found anything out of the ordinary.
I've got a 661 that in high RPM situations, with or without a load, has a hard, dead miss. It's like you bumped the kill switch for a second and then it keeps cutting. It's not M-Tronic. Carb has been replaced with OEM, Coil replaced, and it's been vacuum/pressure tested. No leaks on testing. Carb and coil made no difference. I've tuned it by ear and tuned it with a tach. Tried tuning rich and a little bit lean...no difference. The saw is very low hour. Wires all appear to be in good shape from coil to multi function switch.
Spark plug, air filter, and fuel filter have been replaced also.
Any ideas on what it could be?
