Hi! Leon
You have a point regarding air filter use on water, when Mt St Helen (Washington state) erupted the first time I had a shop in Vancouver BC Canada (about 300miles away) even at that distance, one of the fleets of vehicle that we serviced had to have the air filters replaced every second day( even a week the eruption).
I made the crack about no need for an air filter for a float plane in Canada, but actually much of the time float planes are started on the lake shores with the engine above the ground instead of the water. The other thing about air filters on an airplane, an alternate air source (like a slightly spring loaded flat) should be supplied ( in a float plane case , water could splash onto the element & freeze solid at altitude, blocking air to the intake). On the rotor apex seal subject, I agree with you regarding the amount of wear on the rotor seal slot & seal has to be a lot more than Ed's to spit out the seals. I drove my used engine supplier nuts yesterday, measured 6 different rotors & all were from 2.13 to 2.28 mm, he old me they use these rotors regularly for a long time & never had a problem. Mine are 2.17 to 2.26mm, So I guess I'l have to buy new rotors.
