If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.
If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

If your getting spark and you are getting gas to the suspect cylinders I'd have to say you need to synchronize your carbs.

I am thinking coil or igniter?

One coil fires 1&4 and the other 2&3. Are you getting spark?

To add to the previous question, are the plug wires running to the correct cylinders? Maybe one of the coils is bad or disconnected AND the wiring is incorrect to the cylinders.
Oh, one more thing ... when I added performance coils and wires to my 550 it would intermittently run on only three cylinders. It took a LOT of investigative work before I finally realized that the "coil end" of the spark plug wire to the cylinder that was not firing was incorrectly seated (read "not pushed all the way on to the coil") even though it looked just fine. After pulling it off and re-seating it the problem was solved and the motor ran perfectly.
Hope this helps!
