Hi All!

I mail-ordered a Dubro 2.5" spinner to put on my ASP .91 2 stroke. The openings in the spinner cone are not wide enough for either an APC or MA 14" prop. Also the indented area on the back of the spinner plate is too small for the thrust washer to sit in.

I don't want to modify the spinner as I am likely to create balance problems so I want to return it and purchase another spinner. I know a DB Vortech spinner will have a flat backplate, but are the openings in the cone big enough for a 14-15" prop without modification?

Thanks!
