while we are on the subject of service my 3W-75 is still having fuel drawing problems... i've called Aircraft International and they said it might be a problem with the reed valve being bent or something? i could send it to them but silversurfer said Cactus is the best? what about ralph? he checked this engine out (a while ago when i bought it used, no problems then)... just wondering if anyone has been around the block with all of them and could reccomend the best.... as well as the most reasonably priced, but best comes first.
