While I dont endorse governer removal for clones,however I remove the air vane governer from all my old flatheads! It has never caused an issue with the briggs engines I have, I have four running examples and they run great! You'd have to go full throttle for some distance to over-rev that small an engine! That and they start and idle fine without them! I'm sure others will disagree but let the thread run it's course and sort through all the info and opinions, then do what you think is best!:thumbsup:
