Hello all , and thanks in advance for any and all help . This is my first outboard and it's on a 1960 Larson Pla-Boy that is ready for the water . I just need a well running motor 
Okay , for starters here are the model and ser #'s Mod# 35DE13B Ser # 789843 . From what I have read it is a 1960 which would have the same parts as a 1957 Johnson/Evinrude 35hp (and like half the '58s) .So the issue is when the motor starts it will run but it has a hard miss and will die at an idle and above idle the motor will shutter and keep running . It also does not take the throttle real well . When it is running it will want to die and if I enguage the choke it will pick up again like it is lean .I had someone do some work on it but the hard miss is still there .The carb was just rebuilt and there is a possibility the lean condition is taken care of but when I was adjusting the mixture the motor died ? No spark on both plugs .I started checking it out and found the flywheel key sheered . The flywheel was re-installed but when I pulled it the nut was definitely not torqued ? So.... I am in need of a good manual first .Suggestions ?? Also I need a good parts source ??? I need a new flywheel key .All the ignition parts are two years old with no run time during the two years .They look new. Can I test the coils or should I just replace them .I have read both ways ? Could a coil cause a intermittent hard miss ? I have not checked the compression but I would like to . Is there any trick to this since it is a two stroke ? What should the numbers be ? The motor has a new impeller and it is clean and visually checked out . I am just a novice and would like to check everything possible and make sure she is ready to run . There is also a mystery switch ??? or a ??? on the left side of the motor on the throttle that rotates with the throttle ? One wire goes to ground and the other to the wiring harness . Any ideas what this is ? The black wire that goes to ground is not connected anymore ? Is this important ? I have been told that 50:1 mix is okay to run but I read the opposite .The motor says 24:1 on it and I do understand technology has come along way with oils but ??? Well , that is probably a long enough first post .
Thanks again , Mike
