I heard that using a carb saver, the one that bolts onto the head then down to the carb, can crack the carb. Anyone have this problem? Heard it kind of second hand from a pretty well known engine builder. Is there anything better out there? Maybe it's just if you pick up the engine by the saver? Ran the last of the season without it and had my carb fall off twice. and the bolts stripped out. Had to helicoil them. Thanks for any input.
