Sea Foam Spray with multiple carb throats [SOLVED] Asked by Ben K. In Pennsylvania I have a four cylinder Honda Magna with carbs. Should I take turns spraying into each of the four carb throats?
Yes. With the engine running at operating temperature, spray 1 or 2 short bursts of Sea Foam Spray directly into each carburetor throat. Let the engine “recover” before moving on to the next one. You’ll want to spray each carburetor 3-4 times, alternating carburetors after each recovery period.
