I totally agree that this mod is worthwhile. I do get one sort of "hmmmmm" moment and that's when I have to restart the pump (say, power failure or whatever). Sometimes (most times) it starts up like a breeze, other times I can pretty much do a rain dance and it won't make a difference. On off on off on off bump bump bump come on, start!! on off on off (blow into air intake) on off (blow some more) COME ON!!! START!!! on off on off (Wife asks why you are swearing) on off on off pound pound poof! starts... Not really sure why it's sometimes so finicky..
