i tried it once with the governer spring completely out.and i left the cap off the governer and pushed it wide open with a screwdriver.it didnt rev any harder than what it does now so think its fine.as i stated in a previous post at one stage it would rev its nuts off for some reason and it was revving a lot harder then than it is now.

being the amount of gunk inside the carby from the governer cap falling off all the time i would say some has got sucked in and went thru the engine and it aint as healthy as it should be
