Hello to all. here is my situation. I have a 1977 evinrude 70hp outboard. I recently acquired the remote controls with cables included. although the cables were longer than usual i installed all of it and now I cant get the motor to start. I have adjusted the cables to no advail. my question is if the cables are not the right size in length wood this affect the starting.I have also tryed adjusting the idle set screw. any help would be appreciated. thank you

Length of cables wouldn't have affect on engine running. Check compression.
Check for spark on all cylinders, may need to clean carbs.

thank you for your suggestion. I just found out the problem though. I have a fuel leak at the fuel pump causing air to get in the system.
