Derick Gates SM2K #400 Brava
Based on they previous recommendations and using Alexandre's wonderful pictures I just had the Onan exhaust elbow and manifold joint examined for carbon buildup. Sure enough, the manifold side was narrowed down to the size of a large olive. Up to the time of this examination I did not notice any diminution of the generator running characteristics, but it would have been only a matter of time. I am so glad that it was looked after preventively.
