Take the spring off the choke and put a nyrod on a servo to operate it. U will b glad u did.. I start mine everyday this way. Just put a servo arm with a screw in the hole to make it long and put a ball link in it for the nyrod and ball link to hook onto. I close it with a variable switch so it closes as much as i want. When i flip it it fires uup. I might b a sissy to some people but my Evo 26 starts the first time every time lol ..Take the time to do it and u will b glad u did.
