Genuine Ford Fluid PM-3 Carburetor Tune-Up Cleaner - 16 fl. oz.
It can also be used with great effect to restore tune to carburetors if these have become blocked, stuck, or dirty. When sprayed into the air intake this product cleans all parts of the inlet system, carburetors, port areas and inlet valves. In these areas it is most effective in keeping vital parts moving, and passages clear of gums and deposits, so a smooth system of air flow can be maintained. This is vital because even slight surface roughness from deposits can ruin tuning and cause power losses.
