1991 johnson 40 hp running perfectly update

[MudLake]

Bought this 91 johnson 40 hp for 200 dollars.
It had been burned up and both cylinder were scored. Removed the power head and took it to a machine
shop and bored the cylinders 20 thousand over size. Replace the pistons and rings, Reassembled and found the was a slight miss fire on lower cylinder.
Replace the old ignition setup with a new CDI upgrade. Finished it this morning. Been running it in a barrel for the most of the day.
Runs perfect so far.
Will be taking it to the Rideau river tomorrow.

cheers

If it runs as good as it looks you better wear a chin strap on your cap. Good job. Best of luck. Rick.
