Hobbico makes a "heavy duty" starter for a couple of extra bucks that is suppose to start anything up to a 1.80. I wouldn't go as far as to call it a heavy duty starter, one of these days I will lay out the $ for a sullivan. But it will start my 1.20 four-stroke and G23 gasser with out a lot of greif.
I actually bought that starter and beleive it or not it will turn over my OS160FX (brand new) until I put on the glow driver. Then it will turn it over only if I "help" it. That's with a fully charged 12v powermaster gel cell
Then I discovered that the OS160FX starts most everytime on the first flip. So I now have a pretty good starter for turning over my YS110 and OS91FS engine.
