What type of connections are available for the throttle and choke? Is an electrical schematic provided for keyswitch & other connections?
Thanks! :)
1 answer-
This engine has remote (manual) throttle and choke with connections which are holes provided to attach remote cables which are not included.
This engine does not come with a keyswitch so it does not come with an electrical schematic for the keyswitch. Northern does not carry a key switch for this engine because the engine is designed to be a replacement for an engine that already has a keyswitch.
There are other connection schematic diagrams which are provided in the owners manual which is also available in a PDF on the item page of of the Northern website.Helpful?
