My tiller engine had a carb that elbow broke on. Couldn't get the elbow. Bought new carb and installed it. Surges like hell. Cant figure out how to stop it. Needs almost full choke to run.  As usual, made cheap with no easy adjustment. What is likely cause? Thanks, Tracy

governor spring is 'wrong'? either too 'light' or 'long'.
'slop' in the system allows engine to run fast them slow, fast then slow,never finding the 'happy' point.

other possibility, governor rod is in wrong hole in the throttle plate. I now take a picture or make a drawing BEFORE I tear stuff apart. You 'might' be able to see wear marks in the proper hole, maybe.

Jay, it only had one arm attached to it. I put it back same as old one. I will see if linkage is too tight. The other carb did fine but pissed out fuel in broken elbow. Thanks, Tracy

hmm, EVERY gas engine I've ever worked on has had a light tension spring  with the carb-guv rod sitting inside of it.
maybe post make/model of engine ?
