Hey iv got an old 5hp magnatron B and S engine IV got working again but now it's revs go from full throttle to low,,,,,,all new carb but I knoticed on top of the new pulse jet their is a tiny spring on one of the rods for the revs I'm guessing it is suppose to be hooked to each side but it looks so tiny like fuse wire I can't see it making any difference is their support to be a spring on the top of the pulsejet carbi to stop the serging revs
