Amsoil Power Foam Engine Cleaner (AMS-APFSC)

When your rotary engine has no compression and broken apex seals are not the culprit then this might help remove carbon to free up your seals and springs in order to allow for increased compression.

• Improves starting and performance.
• Cleans dirty intake systems and spark plugs.
• Works inside and outside the engine.
• Recommended for carburetor and fuel injectors.
• Also removes gum, varnish and carbon deposits from engine exterior surfaces.

Directions:

Disconnect your ignition fuse, and spray the entire can into your intake and crank it a couple times to ensure that all 3 sides of each rotor are coated thoroughly. Let it sit for a couple hours then install your ignition fuse and start it up.

This should free up your apex seals if they are stuck in the compressed position with carbon. It may be necessary to install new spark plugs afterward if they are fouled out.
