The hard plastic tube that goes from the air filter housing to the carb. Which end does the rubber adapter with two hose clamps go to, at the carb or or the filter housing. I have seen images with it both ways. Mine is at the carb. At the housing where the o-ring is, does the plastic tube fit over the o-ring and the single hose clamp directly on the tube or should there be a rubber fitting there as well. My plastic tube does not appear to be fully square at the air filter housing. It is not off much, but it is off. I know I have the left one on the left and the right on the right. It is not possible to have the tube round the wrong way is it?
