I have a Briggs and Stratton Model 10T603-0146-H1-1109095 Built in 2011.
I have recently had a surging issue and opted to replace the whole carby and tank assembly (from ebay) as the existing tank was a little worse for wear. With a little tweaking it bolted straight on. The engine starts first pull then it just hits max RPM. I have no control over RPM with the cable, with only the option to rotate the lever so that contact is made with the kill switch.
Has anyone got any suggestions as to why it might be doing this. I have attached a picture of how it is currently set-up, and i'm curious as to whether I have the spring in the right place. Additionally, should the governor control rod have a "spring" type action or it is not under any tension when the engine is off.
