Carburetor/Carburetor CLEAN CARBURETOR IMPORTANT: Never clean holes or passages with small drill bits or wire because a slight enlargement or burring of these holes will change the performance of the carburetor. No other method of cleaning other than solvent should be used. 1. Soak all metal components not replaced in carburetor cleaner. Do not soak non-metal floats or other non-metal parts. 2. Clean all carbon from carburetor bore. Be careful not to plug the idle or main fuel ports. 3. Dry out all passages with low pressure air 240 kPa (2.4 bar) (35 psi). Make sure all holes and passages are open. Do not use rags or paper to dry parts.
