Ok I have a small leak coming out at the manual prime button on the pump. seems to be leaking where the rubber cover meets the metal, can it just be tightened? Also on my HX-35 how muck clearance should I have between tho blade ends and the housing on the front side where the airbox is mounted?

 

as long as the blades dont hit the housing i wouldnt worry about it, there was a thread about as o-ring a while back if thats where its leaking.
