Reply To: Cam Won’t stay in position 1956 Johnson 10 hp QD-17B

The retaining washers cannot be removed without taking out the key.

Won’t be taking out the key or notching the retaining washer to remove the spring.

I will fabricate something to hold down the cam using the flywheel nut to hold the cam in place, the tube sounds like it would work, pvc tube with a washer perhaps.

I’d like to use the timing tool to set the points though setting the points through the hole in the flywheel would be easier though not as accurate from what I’ve read

 

The spring pushing the cam up is surprisingly strong in my opinion.

Thank you
