Have you adjusted the carb? If it has a screw on the bottom of the bowl, then give it a twist while the engine is running. If it's not there, it will be somewhere on the carb body.

Hello andy, & WELCOME to LMF...

If your sure that the carb is cleaned, you should find several different settings on the governor... try another hole with the tension spring...It may have been placed in the wrong spot... :smile:KennyV

If your only getting half the ignition I would have thought you would have more indications than just surging...
I'm sure having both cylinders firing will smooth that engine right out. :thumbsup:
Post back with what you find... :smile:KennyV

the opposed twins are known for surging form minor carb problems....such as bad gas..etc......but theyre great motors!:smile:
