hitachi 200 ex lc manual throttle kit questions

got a 200 -2 machine that's given the regular no throttle response ,,,somewere between cab an controller,,, hadn't had much luck from deer in trouble shooting,,,heard these machines were a regular at this issue,,, was wandering what the manual kit would cost an would it affect the regular opperations since the machine has a computer involved ,,,, how does the pumps an all counter act with the manual governor now since its electrical took out all together, do you still hit witch work mode ya wanta work in speed wise an then just manualy speed motor up. an im guessing the auto idle will no longer work either. any ideas of cost, easy to install, were would ya get one.:Banghead
