Sorry to keep bringing up my thread but I have lots of questions as I go through this motor.
I serviced the starter and tested it by running jumper cables off my truck battery to it. It turned over nicely and was smooth and quiet. I made sure not to turn it for long since I was running a 6V starter on 12V. The Bendix portion also worked as it should raising and lowering as I supplied power to the starter. I assumed that it was good to go so I put it back on the motor and proceeded to break one of the mounting bolts off in the process. I was able to get it out of there and replace it without much headache though.
I finished up the rest of the pieces that I hadn’t cleaned yet and re assembled the rest of the motor. The mag plate gave me some headache due to the cut out wire that runs to the vacuum switch not being routed correctly, but once that was sorted out it went in fine. I also re routed the green wires coming off the coils so that they wouldn’t rub on the flywheel and shortened the black wires. Then I gapped the points to 0.020". I then replaced the plug wires to the correct copper core style and routed them along the motor. I installed new plugs that I gapped to 0.030" and then cut the plug wires to length and installed new ends and boots.



I then put the flywheel on and it was hitting something so I pulled it and found that it was hitting one of the laminations on the coils. I reset that and then put the flywheel back on and then tested for spark. I had great spark on top and pretty good on bottom but it wasn’t as hot as the the top was. Then I cleaned and serviced the pull start and re installed that. I also replaced all the fuel lines, vacuum lines and set the carb and roller cam in accordance with the service manual at this point.

I couldn’t wait any longer time to see if it would start :). I put gas to it and attempted to start it by jumping it off a battery out of my boat. The starter would turn enough to the the bendix to pop up and engage and maybe turn through one compression stroke but that was it. I tried multiple times with the same result so I gave up on the electric start and pull started it instead. After a dozen or so pulls it fired up and idled fairly well for just setting the carb where the service manual said to (1 1/4 turns out on the low speed and 1/3 turn out on the high speed).

I am very happy to hear this thing fire up (not for long since it didn’t have the lower unit on) for the first time in 40+ years but now I am concerned about the starter. Does anyone have any suggestions on what to do to get the starter to work properly? Thank you all for your help thus far in this project you guys have saved me a lot of headaches!
