Ineffective Foam Cleaner

The area around the carburetor of my Homelite 26b gasoline blower needed a cleaning. Since I had some Autozone foaming engine cleaner already on the shelf I gave it a shot. The foam was extremely "foamy" but dissipated within seconds. I waited a few minutes then with a garden hose with nozzle attached I attempted to squirt away the sticky gunk. Results: basically none.

A second application of foam was followed immediately by brushing (tooth brush and paint brush). It still seemed to have little to no effect. Second rinse under water pressure with the garden hose and it looked like the gunk got moved around a little and not much else.

Got out the creamy white hand cleaner in the little tub and that finally seemed to cut into the oily, sticky gunk more than anything else previously above.

Maybe my memory is failing me, but it seems to me back in the '70's that foamy engine cleaner would emulsify the oil/grease/gunk on contact.
