Removed my spinner while in experimenting with different props so got a
nice big brass hub for the front. Turned my electric starter cone
around now can't seem to keep the starter on the hub for more than
about one turn or so, not enough to start the engine. Is there a
different rubber adapter for these?
Make sure you're using the small-hole end of the cone. You need to put more
pressure on the starter against the hub. Don't worry, you won't damage the
engine or break it off the model. :)

And keep the starter aligned with the shaft of the engine ;-)

The other responses are good, and another option is to buy a rubber starter
insert that is made to use with prop hub nuts. That's what I use and it
works great. Tower has them for Sullivan starters for $8.29. See the link
I've used them with Hobbico starters although the Sullivan insert is a
little large, you can still cram it into the aluminum starter cone and it'll
If you have a Sullivan starter or a starter with a standard 1 3/4" cone, get
the Sullivan #S-633 silicone insert... The silicone inserts are kinda
pricey, but they'll outlast the standard inserts 10 to 1...
A little known fact is, you can make your own starter insert from a tube of
dried out 100% silicone caulk. You can rough it into shape on a bandsaw,
but watch out. It can and will jump out of your hands, so don't let your
hand get pulled into the blade with it. Finish getting it into shape with a
stationary disk sander. You can then put a deeper hole in it with a drill
bit, only a small amount bigger than the spinner nut, and start merrily

I have two different inserts for my electric starter, one for spinners and
one for hub nuts. Bought the hub nut one after I learned it was VERY
difficult to keep the reversed insert centered while attempting to start.
The insert for hubs will also start my .91FS so long as I crank the prop
back to just past compression to allow it to get a running start.
Bill's right. Got the Sullivan S-633 insert on my starter, too (it is blue,
BTW). They not only grip prop nuts, but they also grip plastic spinners
much better than the standard ones. I don't dig grooves in my spinners any
My Sullivan cone insert has nothing but a hole in the back...not
reversable. I have hit it with a burr a little to open it up and make a
tapered fit, this seems to work better but it still winds off pretty
quickly unless I hold it very very tightly.
