Default Re: Need help with repair

if the piston is stuck, the throttle and white wire are the least of your concerns.

pistons don't get "stuck." it's either seized, or a bearing's destroyed, or something else that's probably not repairable. you can take the 4 nuts off the head and look inside, or pull it apart. it's pretty simple.

just to ease your mind on the white wire, it supposed to be used as power source for lights or something, and some older motors used to use it to wire up the kill switch.

the kill switch is better wired through the blue and black wires, and these engines have a hard time powering lights.

i actually go in an un-solder the wire and throw it away. most people just tape it up. it's basically useless.
