Magneto Cam and Timming Tool Question

[Kent Cochran]

All,

I am working on a 1952 Johnson 10 hp QD-13.  It will cough & spit but never start.

I think i have a timing issue maybe???

If i had a Timing Tool  and used it after setting the points with a feeler gauge, will the Magneto Cam (Top/high point) and Timing Tool line up together?

I have set the points using a feeler gauge at .020. I have good blue spark on both cylinders. Should i try using a Timing Tool to reset the points? Maybe I need to buy one from Richard W.

I Have good compression 70 psi on both cylinders. Cleaned and rebuilt Magneto it was very dirty. Cam, shaft, Key, and flywheel key way were very rusty. New plugs, wires, coils, condensers. Cleaned old points and reused.

Completely rebuilt carburetor. it seems to be working as should.

My two line pressure tank is also working as should. It holds 3 psi of pressure all the way to fitting for motor.

Thanks, Kent

timing tool is an excellent investment but not used much  if you only have 1-2 motors

just make certain the front coil HV coil  wire is on the top cyl. !
