Hi
I am rebuilding a Johnson 15hp engine. I took the block down to a marine place so they can bore it out.
If you look at the picture below you will see two small whole.
They told me I should get these welded up as this would increase horse power. They said as the piston goes down the cylinders it starts to loose compression before the pistons reach the exhaust outlets.
Is this good advise?
Thanks
James
