Just letting you know. This fix is the best.its been over a week and has worked every time. So easy. After 900 hours the tractor is starting faster and stronger then ever. I finally fix something that I've been dealing with for over 10 years just to sell it. I even put the old starter back in. So if anyone is looking for a new starter that fits a b 2100 and probly more give me email. Ktmhans@yahoo.com thanks for all the help. My part was up to $32 now but no worries.
