RE: Shindaiwa 21cc
aero nut I charged the battery thinking the same thing you said, battery is fully charged and it still missing at high rpm. Well the way i have my sensor i'm not sure if i can move it with it running but i might try that also.
browng300 I have it at 80:1 with Amsoil sabre 100:1 mix oil so that is less oil than at a 50:1 mix. Yes i do have CDI on it and i will try opening up the spark gap like you said. Well this motor is brand new do you think its possible that the ring could be broken? I had Lawn Boy oil mixed 32:1 in it and it ran the same as the amsoil.
Well not sure when i can run it again its raining here and suppose to rain for a few more days. I'll let you know how it does.
Thanks guys
