this is a 2 cylinder electric start, 4stroke that isn't running well. It wont idle and when you give it gas it doesn't get any better. at first I cleaned the carb and both jets since it has been sitting for a year or so- but that didn't help. It seems to be only running on one cylinder. I've been doing some more troubleshooting and I am only getting good spark on one lead from the coil. (checked with a timing light). the coil has a ground and an orange wire from the CDI box, and then the two spark plug leads on the output. I actually replaced the coil as a test- no go.. Seemed pretty simple .. I have the manual and have also checked the pulsar coil and magneto outputs into the CDI and they are within spec.. Any suggestions on the next step? CDI box?

Thanks in advance

Put in new plugs and check the compression. Spark, fuel and compression, it should run.
