I would like to add here that I found the above starters at the R/C Model show flea market and at a yard sale. I also have another Dynatron that I run in original factory configuration that also came from the R/C flea market. I had to put a new cord and rubber around the switch. I got the parts from the Sullivan web site. I also got a Sullivan Hi Tork on the cheap from the flea market that I replaced some parts from Sullivan on. But IMHO the little Sullivan Hi Tork is a terrible starter for it runs too fast at 5500 rpm.
