I have an electric start 1971 Johnson 20hp that is backfiring (single loud pop).<br /><br />When I turn the ignition the motor will crank and then backfire once. After the backfire, I turn the ignition and she fires right up and runs like a champ. <br /><br />It only backfires once before it starts, never when its running.<br /><br />Put in fresh sparkplugs and both have spark. <br /><br />Any recommended fixes?<br /><br />Thank you,<br /><br />James
