G'day Chris, Im always cleaning and painting mowers, but not even close to your level, what a great project. It is a credit to you.
I am interested in the porting you have done.
Any info you could put up about the way you have done it would be much appreciated.
Looks like a golfball inside the intake.
Is the aim to try and get better flow by taking the imperfection out of the casting in the block?
Thanks from Mark
