Whatever you do .... don't blow debri off the top of the piston with compressed air.

I am working through these suggestions and for my engine carbon build up on the pistons here is what didn't work.

Seafoam didn't affect the carbon

Gasoline no affect

Choke and carb cleaner helped a little

Brake kleen no help

WD 40 actually helped a little

Oven cleaner says do not use on aluminum

I can't find CRC Gasket remover any where locally on the shelf.

I have not used, but I will be trying

Transmission fluid

Spray Nine

There is a problem trying to work on this and keep the crums out of the piston gap between piston and cylinder.

Thanks

Greg
