Right cylinder not running

Try replacing the spark plug and the spark plug cap. If the resister in the spark plug cap burns out it will cause a weak or no spark. Most plug caps simply unscrew counterclockwise off of the end of the plug wire. An NGK replacement plug cap will cost between $5 - $10. With the cap off the wire you can check the resistance with a volt meter. Most caps should read 5000 OHMs , any reading higher or lower means it is time to replace the bad cap. If you have spark than, check for fuel flow from the petcock to the carburetor. If fuel is flowing to the carburetor than try disassembling and cleaning clean the carburetor.
